Fry's (Palo Alto, CA) had Zboards for $20 (regular price, no rebate). There were BF2 ones, Age of Empire III ones, and one more, I forgot. Looked small and convenient, but I am broke...
And SF crashes a lot more than BF2 for me, which I guess is kinda good, since it can get either ridiculously addictive or ridiculously annoying (few servers to play on so far). The perma-lag on Iron Gator is also ridiculous! /ridiculous rant
