I finally decided to just get a new spindle- one of the liquid-cooled Chinese ones (this one, to be exact). I've read positive things about them around the web (mostly CNCZone), and the seller has a 60-day money-back guarantee, with free shipping included. Best of all, runout is supposed to be under 5μm (0.0002"), which will hopefully be good enough.
I probably won't have time to mess with getting it mounted and whatnot until after finals, which is somewhat disappointing.
The whole "liquid-cooling" bit still needs to get figured out as well... I'll probably end up with some variety of pond pump and a bucket of water, at least to start with.
