I'll second dtmaonline. I got the best price there about 6 months ago and the tire arrived tmely and in good shape.
I'm runnng Avon AV 45/46 ST tires and love them. A little over 2K miles and the rear looks like it may go 6K. Three track days, one ride through the Tail of the Dragon, and one of the track sessions was wet. They are great tires.
I'm getting fast enough to get my knee down a little, so I'm going to try the AV 49/50 SP tires when I change these out, but the ST series is awesome!
