While this stick will set you back about $180/$190 USD, plus shipping, the wireless rechargeable setup is nifty. The button layouts and measurements are taken directly from an actual Street Fighter arcade machine, and it uses American-style HAPP arcade parts.
Those of you worried about input lag should check out this thread, which shows that wireless technology has come a long ways since its inception, and provides a very close experience to wired controllers, as far as input latency is concerned.
