These work well http://www.cpscom.com/gprod/ux3.htm. USB interface with 3 switchable outlets approx $150. Use visa serial writes to switch.

I just received my PowerUSB (Digital IO model) and have already exposed the dll supplied so I can control it with LabVIEW. You can use the Tools>Import>Shared Library(dll) wizard to make your base VIs quickly. You just need to steer the wizard to the dll and header file in the Development folder from PowerUSB. It will do the rest. (BTW, there's a bug in that DLL wizard. It won't work with any NI Report Generator Toolkit installed, you have to temporarily remove the RGT... I know: )
I'll be making some use of the device so I will post some basic functions as I write them...
