There are several SMD component guides online

the local Robot guys tend to be the most knowledgible on DIY SMT design strategies

Myself I tend to use larger Resistor quad packs (1206x4)  and avoid anything smaller than 0603 passive discretes ( use 0805, 0603) Avoid 0402, 0201) ,and any ICs with BGA packages 

ICs it comes down to availability, DIP through hole IC components are becoming rare and often not available for modern ICs 

Last time I designed a PC board for through hole components was 1999 for Ernie Ball Sterling Bass 3 band active EQ "banana" board


compare to my recent Apple mFI approved design here

[mosaicmerc] over on hackaday.io has upgraded his Rigol DS2072A oscilloscope to a DS2302A, turning an $800 oscilloscope into one that sells for $2500, with all the bandwidth, storage depth, and options of the more expensive model.
http://rheslip.blogspot.ca/2015/09/software-spectrum-analyzer-for-rigol.html
Rigol o-scopes have a long and storied history of unlocking, hacking, and upgrading. The original hack that put Rigol on the map was the DS1052E upgrade that turned a 50MHz scope into a 100MHz scope. The latest low-end Rigol scope, the 1054Z can be unlocked in software to become an 1104Z with 100MHz of bandwidth, SPI, I2C, and RS232 decoders, twice the storage depth, and more triggers.

It appears Rigol’s engineers are designing their products to capitalize on the hacker’s proclivity to buy their tools to get the ‘free’ upgrade. This, of course, sounds just slightly insane, but no one seems to mind.

The process of upgrading the Rigol DS2072A scope is documented over on the EEVBlog, and requires only a USB cable and a computer with the Labview Runtime Engine installed. It’s literally as simple as pressing a few buttons; a far cry from the previous keygen method that was also engineered over on the EEVBlog.

I have a hacked 1052E on my bench.  It's been doing the job here for several years.

No reason not going SMD. Just a matter of initial investment. Buy a good magnification lamp, SMD Tweezer and a great soldering station (Weller etc.) and off you go. Unless components are VERY small it's faster soldering SMD when you get use to it. It's better for the enviroment also, less lead, no cutting etc...

Parts getting placed on wrong locations can drive you crazy


It happens a lot on 1st production runs, at my work we order the Assembler to build a few boards , and allow me to test for BOM (Bill of Materials parts list) errors, then I approve the 1st article "Gold sample" and return it to the Assembler as a reference, prior to the mass production run

Also helps to repair dead electronics, or reverse engineer existing circuits

Get the SMD (Surface Mount Device) Code Book!
https://www.sos.sk/pdf/SMD_Catalog.pdf

Get a in circuit LCR capacitance checker , I use an Agilent LCR Meter



with tweezer probe'

Smart Tweezers ST-5S Digital Multimeter with Spare Ergonomic Bent Probes



Smart Tweezers ST-5S are a professional quality LCR-Reader. Unlike traditional LCR-meters that require both hands and extensive set-up between measurements, Smart Tweezers is able to automatically determine the type of component as an Inductor, Resistor or Capacitor while measuring with a high basic accuracy of 0.2%. When a Surface Mount Device or older through-hole component is grasped between the gold-plated stainless-steel tweezers, Smart Tweezers will identify the component and automatically select the best test range and signal frequency for that component. The measurement values, type of component, secondary values, test frequency and mode are displayed on the screen instantly.
The ST-5S also has manual test parameters within the extensive menus. Every task can be specified with the ability to select the test range with 100 Hz, 120 Hz, 1 kHz and 10 kHz test frequencies, L, C, R, ESR, D and Q measurement test modes; component sorting or any work involving a PCB has never been easier. The unique design and fast, automatic measurements allow users to focus on the task at hand. Navigated with a joystick button, users don't have to enter the menu to change the measurement mode or test frequency.
Smart Tweezers comes in a hard-shelled carrying case, with a Li-Ion battery that holds an 80 hours of continuous use; the 1 oz. weight makes the device ultimately portable. The ST-5S comes with an NIST traceable certificate for professionals who require their equipment to be calibrated annually, a hard-shelled carrying case, and spare bent tweezer probes.

Features on Smart Tweezers ST-5S:
Automatic and manual L, C, R, ESR, Q, Z and D measurements
Automatic and manual test range selection
Adjustable test signal levels
Diode, polarity, and short testing

I found this handy when I wanted to do some work at home and didn't have a "real" function generator:

Debugging audio gear , biasing Tube Guitar amps, and occasional embedded controller development, This unit works very well for my needs.

The built in Signal Generator, and decent oscilloscope and fast intuitive controls and operation and multimeter as a bonus makes this permanent place in in my mobile audio electronics tool bag

not bad for battery power 6 hours per charge  @$220
