The Wizkids haloclix work OK, but they're a bit big. I have a few of the Mcfarlane ones and they're much better, they've bene OOP for a few years and are getting expensive, but if you watch for them you can find them for $10 to $20 on ebay and such. The "Halo 3 series 1 warthog" is indeed the one you want to look for
