One place I know, which I can buy over the phone very promptly, but are
slow with send a price quote through email:

www.roton.com

Their website is nice, as it has probably all the technical data you
need to use thier products.

I'm not sure, however, about the lead error of their stuff...I think
they make everything with precision roll-forming, which is less
expensive than ground ballscrews, but if I remember correctly...no wait,
I just picked it out of the website:

Lead Error
The deviation from nominal lead resulting from manufacturing variations.
Standard lead error tolerances for Ballscrews are .010 in. per foot.
Lead errors for Acme, Hilead® and Torqspline® series leadscrews are .009
in. per foot with precision tolerances of .006 and .003 available in
selected sizes. All tolerances apply plus and minus, however, thread
rolled product errors are generally the same throughout the entire screw
and can be easily compensated for with appropriate profiling software.
