Was about to say, ask your instructor if you get a school discount. Friend of mine got 40% off with their school discount on Snap-on tools. After school though I recommend Husky from Home Depot and Harbor Freight tools.
I've had my Husky tools for a long time. I haven't broke any of my sockets. I did break the 1/4" and 3/8" extensions and wore out the 1/4" and 3/8" ratchets after 15 years and replaced them easily. Friend has 1/2" drive Husky impact gun that ran circles around the snap on and Mac tools guns in his UPS shop working on their tractor trailors. Broke bolts loose their's couldn't without having to step up to the 3/4" or 1" impacts. They had a Hurricane compressor for air supply.
I recommend staying away from craftsman. You'll be going to the store constantly turning in sockets for the lifetime warranty.
I have alot of Harbor Freight tools. Their tools are really good for the money, especially with the coupons and lifetime warranty on hand tools. Seems like I have at least 1 of everything they sell since I'm there constantly. They also have alot of specialty tools (compression tester, fuel injector noid tester, spring compressor, etc.). There are some items to stay away from though. Just ask, I can probably give you a review on it.
Also check out some Ingersoll-Rand tools. They make great impact guns, though I use the Harbor Freight Earthquake impact myself (basically an Ingersoll-Rand copy). It's on the heavy side, but lots of power.
If you'll be working on any Honda's, you'll need an impact screwdriver and some heat for their brake rotor screws.
