Anytool you NEED at the time, is worth while.

I started building my tool set when i was 14. At 36, I think the only thing I'm missing, that I'd actually use, is some body work tools (sanders and hammers) and a lift. Over the past 24 years, I've had 100's of "Damn, I need that tool that does....." moments.

Outside of the standard stuff (sockets, screw drivers, pliers, hammer, Jackstands ) I'd go with snap-ring pliers too, as the most vaulable.....both the compression and expansion types

.....Ofcourse, if your removing snap rings, your probably going after something with bearings. So, you'll need a brass punch, a dead blow hammer and a bearing puller.....maybe a hydraulic press and some dies for the various bearing sizes....a slide hammer is nice to have too.....it builds quickly.

I'm not particular on brand. My original set of tools was snap-on.....which I like, but the wrneches are too thin and dig into my hands when pulling hard on something. Mac's have a wider grip and are more comfortable. As long as it has a lifetime warrenty, and does the job, I'll generally buy the cheapest or easiest to find.
