I have almost all Snap-On (yes there really is a difference) but they are very expensive for the most part. It seems like everyone else has gone to made in China, including Craftsman. Sometimes you can find good tools at auto parts stores. I like the Gear Wrench tools. Lowes used to have decent tools, but now the sockets are junk. The combination from Lowes are not bad. Some tools from Harbor Freight are worth buying if you only use a few times a year. You can get an entire tool set for less than $100.
Your most expensive tool will be a good torque wrench. From Snap-on, you will pay $300-1000 depending on size. Digital is most accurate, but a lot more $$
I would start with getting a set of
SAE
-1/4" 3/8" and 1/2" drive sockets.
-1/4" 3/8" and 1/2" drive Ratchets
-1/4" - 1" combination wrenches
-1 3/8" combination
-1 5/15" socket
-30mm socket
-10mm combination
-Allen wrench set
-Allen socket set
-1/4" 3/8" and 1/2" Extensions in several lengths (sometimes wobble ones are nice to have, but will not hold up to as much torque)
-1/2" air impact (buy the earthquake from Harbor Freight, $70 on sale)
-Air compressor, at least 20 gal with enough CFM to power air tools
-Dead blow hammer
-Torque wrench in at least 3/8" and 1/2" drive
-And you will need a tool box for the tools. No need for a $20,000 Snap-on
