Well, I did one, not with a kit but rolling my own, and it DOES work!
Depending on what condition your machine is in (mine was fairly well
worn) you can get results from mediocre to quite good. I did use
high-quality ballscrews, encoders and servo motors.

[If everyone hasn't talked you out of it already, I found a company selling
Bridgeport stuff at the Westec show, who had a new preloaded nuts/
precision-rolled ballscrew set for the x and y axes of a Bridgeport series
1 selling for $650. They also offered other sizes of these, so they might
be worth your checking out: High Quality Tools 34940 Lakeland Blvd.
Eastlake, OH 44095 1-877-372-9227. They stock odd parts for manual and CNC
Bridgeports as well.]
