I have tried that one time to tap into the potentiometer (not sure if that's what you're talking about with hobby servos).

Eventually you do want to fork out money for more expensive servos as those cheap 9g blue ones don't cut it, start to get hot/melt when used in a more serious robot application. Granted at that time I was using one cell so maybe that was more current. At any rate when I switched from $2 to $10 servos (especially metal gear) it was noticeable. The price matters when your robot has 12 or 18 of these servos on it.

Thanks for the links, as my robotic projects get more serious I do want positional feedback, term I picked up from a fun book "proprioception"
