9x20.

5 or so dift suppliers carry it, incl HF, Grizz, Enco, etc etc.

http://www.bedair.org/9x20.html for what can and in some cases,
should be done to it to improve it (beefing up cross-slide, adding
reverse and may be going variable-speed). It is an incredibly
popular one and there are tons of resources on the Web.

If you go that route, $700 @ HF - 20% off, pick it up @ yer
local store for instant gratification.

Or, if you innted to stay small in worksizes, go with The Lathe:
8x12, www.mini-lathe.com . Again, carried by all the usual
suspects. It is even more popular than the 9x20 and again,
lots of resources on the Web.

Both are perfectly useable outta box, right after removal of
protective grease.
