      I know I'm chiming in ait late here ... but my bench top mill is an   
   RF45 clone , and it's been more than enough mill for all my projects .   
   Including multiple gears cut , end mills sharpened (with a fixture) and   
   all kinds of other projects . I highly recommend a rotary table for   
   indexing , mine's 90:1 gear ratio .

   Have you tried boring a cylinder accurately with it?   
      
   My 1950's Clausing 8525 bores slightly tapered from wear that allows the   
   quill to deflect more from cutting force as it extends down. The later model   
   has separate bolts for quill clearance and locking, on mine one bolt does   
   both. It's better when boring by raising the knee.   
      
   The wear wasn't a concern until I reconditioned a hydraulic pump and tried   
   for minimal bearing clearance.   
      
   The RF-31 I ordered from MSC for the company shop wasn't quite square on any   
   axis, and the tee slots weren't parallel to the travel. 0.005" was about the   
   limit of its accuracy. It was adequate to replace a badly worn drill press,   
   that's all. When I needed higher precision (rarely) I did the work at home   
   on overtime.
