I bought from the manufacturers (on Ebay) but the last post looks a good price! I'm trying to find metal gears for these servos. BEWARE! NEVER move the control arm, or the control surface attached to it, with these small servos! YOU WILL STRIP THE GEARS! Only ever move them the correct way, from the Tx/Rx! I have realised that this has been my main problem. Be careful when putting model into the car or just handling it. They break so easily!
Another "be careful". The spindle that the arm gear fits onto is "keyed". The gear will only go on one way. Don't force it!
