I have a G9729 12x36 and I don't think I'll buy another anytime soon. Having to tear the whole machine apart to get all the casting sand and grit out is a night mare. Had to replace the carriage shuttle spur gear cause it was rusty and was roughly machined and pitted. The replacement gear was same condition minus the rust. In order to get the cross feed to work smoothly I had to remove the gibs and sand/polish to make it work smoothly. If your thinking to use it "out of the crate" you had better forget about it! It will take a week or more to get it to work semi-accurate.
