Words from Snap-On fan here, sorry
Excellent post, Dl5treez. When I was going to aircraft mechanic school, the Snap-On rep came around and offered 50% discount on anything in the catalog, including Sioux air tools. The Mac rep came around and dropped off some catalogs and was never seen again. Of course, it didn't hurt that the Snap-On rep was an
extremely attractive blonde gal. When she would come around, everyone would go

She was from "Snap-On Corporate", not a driver with a truck. She would take our student order forms and we'd pay by check or credit card and the tools would be shipped to us.
I bought as much from her as I could afford, but unfortunately I had just bought a house, and I didn't have much disposable income. I bought a top and bottom rollaway from her too, but she was only allowed to sell certain models of rollaways, so I wasn't able to get one as big as I wanted. But I bought as much as I could, figuring these tools will last me the rest of my life and I would never be able to buy at those prices again. My only regret is that I wish I would have bought more!
Anyway, to add what Dl5treez said in the last paragraph of his posting, think about getting 2 sets of combination wrenches and sockets. I'm sure at your school there will be tool company representatives offering discounts. Take advantage of them.
One of the guys in my class was an E-Bay fanatic, and he bought a lot of tools on E-Bay. He bought an air drill, used it during the quarter we did sheet metal work, and then sold it on E-Bay for more than he paid for it! He also bought some tools at a pawn shop at very low prices.
The vehicle mechanics at work (they work on semi trucks and aircraft loaders, forklifts, etc. ) each have their favorite brands. One guy swears by his S-K tools. Another really likes his Matco ratcheting combination wrenches and he uses them all the time.
Also, get a ratcheting screwdriver, they're really cool! I'm sure all the brands make them, but I have the Snap-On. It's a set in a plastic box with different length extensions and tips. I bought a second one to keep in my truck. Love those soft-grip handles!
In the past, I've always had Craftsman tools, but I much prefer my Snap-On tools now. One thing that really stands out as a difference between the two is the wall thickness on the sockets and especially on the box end of the combination wrenches. Many times at school my fellow students would ask to borrow a Snap-On wrench or socket from me because their Craftsman wouldn't fit into a tight space to get on a bolt or nut. This happened ALL the time!! They were cool and we all worked together, so I didn't mind. But that there was proof that the instructors were right, Craftsman tools can't get into tight spaces like Snap-On and Mac can.
Sorry if I'm waving the Snap-On flag too much, but I'm a happy customer.
