not sure how valid this is as a reference, but here's my experience: in '02-ish, I paid $1200 for my '93 SN 650, with pipe, head, impeller and trailer, all in mint shape. I got it from Buffalo, NY and it sat on Ebay for a few days prior. Have prices gone up considerably (assuming that ski is stock and no trailer), or is the seller trying to take advantage of the summer frenzy?
