Thanks for all the great replies. That was what I was looking for. I know you get what you pay for and the Ebay, Amazon's and other websites can say whatever, right or wrong. That was why I was looking for some of your great feedback. I looked at the mfg's websites initially and wasn't able to make heads or tails out of them. Not like a encoder spec is defined at least, that I can understand.
I have some other ideas on how to accomplish what I am looking to do, a bit more on the mechanical side with a encoder, but hopefully still simple to attach. Some simple string-pot type encoders.
Thanks again.
