Jon - I can buy a good "precision rolled" ballscrews with adjustable
anti backlash nut and wipers for little more.

There are GOOD rolled screws out there and they are not that expensive.

0.001 per foot is not that precise, it's grade 3. That's 25.4um per
foot, the screws I use are 0.052um per foot (grade 7;) and are the ones
priced here.

As an example..

16x4mm is $32 per foot, $91 for the screw and $18 for the seals.

I can also get the ends machined and threaded by the supplier to suit
preloaded bearings for another $40. (Worth it IMO).
