It's not a dated gun. '08 and '12 PTWs are sought after items within a certain market. The Michigan Airsoft community just probably isn't that market.
The vast majority of Michigan airsofters won't shell out $300 for an AEG, much less $700.
My suggestion would be to wait until Tackleberry's PTW Forum gets back up and running and post the gun there. You'll definitely find a buyer.
