Found this on eBay: BOTCON LOT 2005, 2006, 2007, 2009 - eBay (item 160414456670 end time Jul-14-10 20:58:10 PDT) While I do admit the 2006 and 2007 sets are very desirable, that price is absurd. You also have to factor in the other 2 sets. The Virulent clones (from the 2005 set) are the only chase pieces. Ratchet's price seems to have settled down some. The only bit worth a darn from the 2009 set, thus far, is the Sweeps 3-pack. I think any price over $5000 seems ridiculous for all those sets. Most of that can be attributed to the 2006 set too.
