WARNING FROM HEXTRONICS:
Appearing servos can be found on eBay and other Asian sellers, but be warned, they do not contain Taiwan / Japan components. HexTronik (the manufacturers of these servos) have two standards, one is for local sales, and the other is export quality with imported connectors and resin gears from Taiwan and Japan.
Our HXT500 and HXT900 are export only, not built for the domestic market. You don't get the same quality servo for less, everywhere!
