I have a VM32L from Amadeal.
I have been happy with it over the least year or so. It is powerful (I can cut 1mm DOC in steel with a 63mm facemill) and reasonably accurate.
I say reasonably accurate as I can never tell if it is the machine or my fumbling that makes things go wrong! I can cut within a thou (0.03 mm) on a good day.
I would say that service is reasonable. In my dealings the guys at Amadeal don't have the same depth of engineering knowledge as ARC do but they are responsive to issues.
Frankly, I would expect all the machines you can buy in this country to be roughly on a par (like for like, I mean). There are only 3 or 4 suppliers in the far east for most of them. It's down to details and price.
