Buyout at 3.5, been listed for 1 month, and has 217 views. None of the unusuals that were offered on it are priced.

Sold at 3.48 and 3.8 makes me believe that 2.8-3.4 is a solid range.

There is only the one listed on Outpost. None listed in Classifieds or on Bazaar.

As always, tips and criticism are appreciated.
