I was poking around Craigslist (as one do) and ran across a 2004 R1100S, 44k miles, bags, for $1500 because the ABS is hosed. If I could figure out how to get it home from there...

(Not my bike, no relation to seller, but it sure sounds like a good deal.)
(On second glance, I don't like the oil staining around the final drive boot, but still...)
