I've been using Trex-600 landing gear on mine. They're a little beefy and hold up to rough landings quite well. I drilled extra holes in mine so they'd line up with my frame screws.
Google search for "trex 600 landing skids" and you'll see all the pretty colors they come in, and they're cheap. Not to take away from the Parallax ones at all, but if you're worried about breaking skids these are meant to hold the weight of an 8lb helicopter during hard landings. I think they weigh about 80g per pair.
