I'm looking to build a reliable featherweight but don't know where to start

Welcome Sam. I'm sure plenty of advice and help will be given. I'm in the same boat as you in that I'm starting a feather build for my 1st bot.
From reading posts here it seem that the botbitz 85a controllers converted for brushed motors are popular but also hard to obtain.
I'll be creating a build thread once i get a design i want sussed out. Like you im going for 4wd driven off belts system to allow some forgiveness to the motors.
It'll have a BB85A each side to handle the load. Failing the availability ill try and pair up the 30A versions if possible. I'm stuck on weapon at the mo but I'd love to do either a lifter or a drum spinner.
Good luck in whatever route u choose .
Andy
