I'm still searching too. Stores are picked over.... only OTC Hans and about 2 VOTC Hans are the best I could find.
I've just gotten home from a road trip from NE Ohio to Maine (by way of Boston) and back, making a few WalMart/Target stops along the way...and the only conclusion I can make is that New England is as ruled by Dagobah waves as the Midwest.
I CAN'T FOR THE LIFE OF ME FIND THE BESPIN WAVES!!
Well, okay, that's not entirely true...I did in fact find a Wal*Mart in Scranton PA that had three Lobots warming the pegs (and nothing else, no Aaylas, no Hoth Troopers), and I relieved them of one of him.
And my fiance' had the good luck to pick me up a nice Spirit Obi and Bespin Luke (as well as an OTC Yoda that has the most spot-on paint app I've ever seen. Museum quality!) the other day, so I can't complain too much, I've gotten just about everything I've been looking for...
...except...Cloud Car Pilots...
