Some time ago, I got the Custer's Last Stand playset produced by Toy Soldiers of San Diego. TSSD is quickly becoming one of my favorite producers of toy soldiers. The quality of sculpting, poses and level of detail on the figures are fantastic. Very high quality, but at the same time, they retain an element of "toyness" where I'm not afraid to get them outside in the dirt, and wouldn't haven't a problem with a young child playing with them.
Another great thing about this playset, is you get so damn much stuff with it. The wonderfully sculpted foam hill, lots of cavalry figures and horses, and of course tons of Indians. When putting together a playset, Indians at Custer's Last Stand are like Mexicans at the Alamo: you can never have too many.
When I first got it I set it up on my dining room table. Not enough room for everything:
Last weekend I got these guys outside and got a few more shots:
