Do you need wireless? If not, you can plug your AB right into your sync connector (if equipped) or hot shoe adapter. I've got cables of varying lengths (up to about 16') for this. It's hard to beat the reliability of wires. Of course, they can become trip hazards also.
On the wireless side, it's even harder to beat the PocketWizards as others have mentioned. I'm sick at the moment. I didn't realize I'd left batteries in my receiver and now it doesn't work. Even the transmitter stopped. I might see if PW can fix them. Otherwise it looks like I'll be buying some new ones. The basic model now runs for $100 each and they're transceivers. You don't have to buy a separate transmitter and receiver like I did.
PWs are awesome. I've used them in studio and sports settings w/o any issues. I might have some pics somewhere of the gym setup. I used a Super Clamp to position my AB800 near the basketball goal and got some great shots from the sideline.
I've actually been tempted to try the Yongnuo stuff also. Their manual flashes get pretty good reviews.
