I have about 17 of the Bonus Battle Droids and 12 out of the 15 Bonus Pit Droids. I haven't had to much touble as far as getting the BBDs since I bought them from the ToyShop, Toy Palace and Ebay. The ones right now that are hard for me are some of the collection 2 pieces but mostly because I don't have the money to spend on them right now. The hardest Bonus Pit Droid was Sidous but through the Toy Palace I got all of the different kinds but one was on a damaged card along with a damaged BBD Yoda, so I have to eventually replace those figures. Hopefully at C3 some dealers/collectors will have some for sell at a resonable price.
