I recently came across this interesting ad on ebay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320547035193&ssPageName=ADME:X:eRTM:US:1123 It's only $1! But it comes without cable. Does anyone know whether:1) this is a buckling spring?2) if it's a buckling spring, does it use regular keycaps?3) what kind of cable is required?I tried asking seller and actually got a ridiculous answer: "only $1"DUH, even if it is only $1, shipping is $12. And cable could be another $20 shipped if it is a proprietary format unique to this Mighty M. So before anyone does any buying, I think we really need to know as much as possible about this keypad.Please share all the info you have! There are plenty of numpads to go around, no need to charge onto ebay and buy right away.
