After reading the mammouth 200 page thread from Hoss (good work dude), I decided to get one of the BF20 clones. Here in the UK I bought a Chester Champion 20vs for around £850 delivered.
I got the thing out of the crate today and on to the bench.
First job was the three-bolt mod, which interestingly enough, needed no grinding down of the extra bolts, they were a perfect fit.
A couple of other things I have noticed so far is that I am hoping have a full 200mm of travel on the Y-axis if I remove the bellows, and also that the motor is 850watt. One more thing is the quill travel is 52mm rather than the quoted 42mm on the Chester website.
I will update this thread with more specs as I strip the machien down.
