Need a new servo.

[Burty248]

I had a as17 that all there gears inside are completely gone, i have a spare but i think that wont last very long, so i am looking to buy a new one.

Had a quick look on model sport and there are loads and i don't really know what im looking for.

So what servo should i get im not looking to spend that much or is it just work buying a load more of the as17 cause there cheep?

What servos have a lot of spare parts like gears available if there shredded that are still in the low price range?
