I tend to be the contrarian. If I am buying a tool I know I will be using a lot, I will buy a good one, usually Park, Craftsman or Kobalt. However, for tools that I am going to use very infrequently, I will usually go to Harbor Freight.
Expensive tools are an absolute necessity for a professional. However, I only spend about 100 hours a year working on my bikes. For most things, Spin Doctor and Harbor Freight are just fine. I have never had a Harbor Freight tool break or wear out on me. I can't say the same for Spin Doctor. Do not ever buy a Spin Doctor work stand. If I had done a little bit of research, I would have known better. On the other hand I have a set of Spin Doctor cone wrenches that I only use once or twice a year that work fine.
