Well, Greg, I'm sorry I bought such a piece of *****. It sounds as though you think Adam has as well. I bought what I could afford,, not everyone can spend over $600+ for top of the line air. And lucky for me, I AM a "home user." Thats probably why I bought the base model.
For the five months I've had it, I've pulled 1 rear end, 2 moters, 2 trannies and many more huge rusted bolts with no problems. And it still works fine for my periodical use when needed. Sounds like adam is pretty happy with his so far also.
I just think you could have shared your 'expertise' in a kinder way instead of wishing us good luck while we wait for our crap to break so we can have fun fixing it.
Back on topic.. I have always heard electric grinders are much better than air grinders. Basically because they have more stamina, since there is no limit on electricity. I think you would need a huge air tank to continually run a grinder without it slowing down. I bought a $20 electric 4 1/2" grinder from HF and it still runs strong after 5months of heavy use. Also nice how you don't have to wait for your air tank to fill up before use - plug in and go.
