Gecko G420's question

Gentlemen,

Does anyone know what type of feedback the G420's are expected to use? Hall effect or encoder?

Will the G420s save money on servo motor cost? I understand the benefits of eliminating brushes and commutators, but are there many sources of motors for them?

Someone mentioned that the brushless motor is kind of like a DC permanent motor turned inside out, I think. Can someone take a three phase AC motor, and make a new rotor with permanent magnets glued to the rotor and make their own motors? Maybe a dumb question, but I thought I'd ask. I have re-glued permanent magnets back on some motor housings in the past. They seem simple enough.

How about some more discussion on what this new development will bring to the hobbiest CNC guy.
