I searched completed listings on eBay and found this list:
http://www.ebay.com/sch/i.html?_saca...mplete=1&rt=nc
Only the prices in green indicate an actual sale. Red prices mean they didn't sell. I didn't go through the whole list but did see that one sold for about $1850 while others sold for closer to $3000.
For me, it's not a good sign that so many of these machines are for sale on eBay. The list is quite long.
