I've tried searching, but I couldn't really find anything. I have to assume this has been discussed, probably at length somewhere, but I just can't seem to find it. Where can I find cheap but decent wheels? I don't want to spend $60/ea. for my first project. I'd like to be under $100 for all 4. I was thinking like Harbor Freight dolly wheels, but I read their bearings fail super fast at high speeds. Can I get cheap but good replacement bearings for those sort of wheels, to still come under $100 for all 4?
