I think these are not yet available in the States. Earlier sets of groundpounders are available from Michigan Toy Soldiers but the pilot sets are not listed yet. However, I would be willing to bet they will carry them once they are available. You might e-mail them to see if they will carry the pilot sets.
BTW, if you register with Michigan Toy Soldiers you become eligible for discounted prices on just about everything- usually 10-20%. I've never ordered anything so I can't speak to their service. I did meet the principals once at a show and they seemed like standup guys.
