$550 for one:
appleton.craigslist.org link
(has at least lasted a day so far.)
There was another one recently for $350, but looks like it sold (down in IL). I know of one other that recently sold for ~$600, and it was so-so.
Have seen very nice ones sit unsold at $1000-$1200 too.
It really depends on cosmetic condition and location.
