Encoders

Well, I've figured out that the servos I have are fitted with
resolvers instead of encoders. I read an earlier thread about
resolvers Vs encoders so I know that I will need to replace them. I
saw Jon's recommendation of Sumtak encoders. Are there others I
should look at. I got a quote of about $150 each from Renco. At
that price it might make sense to sell the servos I have to someone
trying to keep a Bandit fitted machine alive and buy new servos with
encoders already installed.

On another note. I have a complete set of Bandit controller boards
that I should sell. Other than eBey , Are there good places to sell
this kind of stuff?
