Jcadwell,I'm looking at the Poly-Scientific motors on the HomeCNC site
Don't get my larger servo motors. I have a few cases of the "Cheap Servo" motors that I got, and I am doing some machining to fit encoders on them. They will work great on your Taig! They are 360 oz/in Peak.
With the cost of the motors, encoders and machining time I'm going to be offering them for $75.00 each plus shipping. This should save you a few bucks over my larger ones. Send me a note if you are interested.
