I'm looking for a USB solution that will work with 32/64 bit WIN7/8,

The simplest and cheapest USB rotor interface I know of is the "ST1". 
It's JUST an interface, with no control buttons and no display.  Price 
is $39 for the assembled PCB with no enclosure.  Mine was shipped in a 
very small box from India.

I never understood why so many people are so eager to pay much more 
money for a rotor interface box that has buttons and a display.  The 
computer screen and mouse can do that!

The interface emulates the old "EasyComm" interface.  Real-time azimuth 
and elevation are displayed in a separate small window on your computer 
screen.  Manual control of the rotor can be accomplished using the 
SatPC32 Rotor menu.
