However for some balance, I have had great customer service from Grizzly, and all my many Griz tools have served me well! They have quickly resolved the few(and I do mean VERY FEW) issues I have had quickly.
I would suggest you call Grizzly. I am sure they can answer your questions!
Remember unhappy customers are usually much more vocal than happy ones. Check old threads hear and you will find 90% or more of the negative opinions on about any product are from the same handful of folks. The exception being the truly bad products, which usually find universal disapproval!
As for Chinese sourced.. most of the few remaining "USA built" machines are imported.
I have found that hand tools are the best choice when I want to make mistakes at a slower rate of speed.
I don't suffer from insanity. I enjoy every minute of it.
