Just found this via kipper: http://cgi.ebay.com.hk/ws/eBayISAPI....1&category=633

Surly we can make these for allot less ? is there anything special inside these i may not know about ?

Zapp also wants: http://www.slidesandballscrews.com/i...2708d04a19410a

So all that is really needed is a nice case to mount the hand wheel and switches in or is there somthing special inside these units ?
