Chris,
These are the folks I bought mine from, and they work great. I did have one to break on me after about 1 year of use, but it was my fault because I did not have my motor mount perfectly in line, which caused binding on the end of the lead screw (flexing due to misalignment) until it finally snapped. But it was nice, to be able to simply go to their website and order a replacement.
Here is the link to their website:
ACME LEADSCREWS | PTM Precision Tech Machining

Note: I originally purchased from them off of an ebay auction while building my machine. When the lead screw broke, I thought that I was sunk! However, a quick search for the company name took me to their website, and I had my machine up and running again in less than a week!
