Bought one of these used myself about 5 years ago, it was a total disaster. Check it under power! We didn't and payed dearly. Seems Fadal glues "turcite"(dense plastic) onto the gibs to reduce friction, the glue failed on nearly all the gibs resulting in about .06 play in the head assembly and in the X axis on the table. Also found under the way covers that some of the plastic oil lines had cracked so way oil was never making it to the box ways, just pumping into the craddle area under the table. Best of luck.
