If you are a professional mechanic and use them every day, Snap-On is well worth it. For everyone else, there are much better value options out there. I generally steer people to Gearwrench and recently, Tekton seems to be a good value. (Disclamer, I have been a Snap-On addict for going on 22 years now and own pretty much all of their hard line, and many countless dollars of specialty tools)
