Well, not exactly "buy" but a guy at work noticed a 3D printer in the trash at the university dorms, and thought I might want parts from it. I tried it out and couldn't see anything wrong. I tried a test print that tried to work, but it was loaded with ABS but the print was set for PLA. So, today I downloaded cura, saw it didn't have a post for this printer (Stanley Model 1) and found a download for the config for the printer. Then I downloaded a random object from Thingiverse and it worked remarkably well!
So far, total cost about 3 hours of my time.
