I'm curious about the Cirrus digital line of servos. I tried the cheap-o Tower Pro servos, and they were horrible. I had to send them back to the Chinese Ebay seller I got them from. They had poor centering, poor resolution, poor speed, and they over-shot the stop point on high throws to a very perceptible degree. The Cirrus servos look suspiciously similar, so I hope they're not made by the same people...
