If you know how to handle a soldering iron (and you clearly do), you can 
build an USB SO2R switching device for peanuts, based on OTRSP (Open Two 
Radio Switching Protocol).

You can check the description of K1XM 
http://ncjweb.com/features/julaug10feat.pdf or 3V8SS 
http://kf5eyy.info/technical.htm (section KF5EYY SO2R Controller), or 
roll your own.
