Heh, 3K in Snap on wont go far :-P My toolbox alone was almost 10k.....its plain SICK what tools cost these days! 3k will buy you a metric socket set from 6 to 27 and american socket set from 1/4 to 1", a 3/8 ratchet, a 1/2" ratchet, combo wrences from 5/16 to 1 1/4 and metric from 6 to 30, a screwdriver set, a few pairs of pliers and a smalll toolbox. Maybe an air gun and air ratchet. I dont think you'll get much more than that!
TurboMike I believe is a ASE Cert world class tech, while I am merely a Auto Master plus L1. Up for recert in July, provided I pass them all again, will be working on the truck stuff next. I previously had no need, but now I am working on some larger trucks and figger it cant hurt.
While cerftification is great, dont put too much weight on them. I say this because I have seen some real dimwit masters. Theres nothing better or more important than OTJ. And 1/2 the problem is when you actually work on these things, the tests become more difficult because the way you may do things, isnt really textbook after awhile and makes ansering textboox type questions tough. (Personal experience)
Good luck with your education. A good tech is hard to find and if you are good at it, you can go pretty far with the right shop.
