The DVDO VP30 would be the best bet in your situation I think, sense you have more than 1 kind of input, and you only want 1 kind of output.. I would go with the vp30, I was thinking about getting one for my system, sense you can do any input/any output with that product. One other option is find a reciever/processor that will convert anything to a hdmi out.. but then you will have waisted that money.. I would rather wait a bit longer and buy 1 thing that I wanted, rather than buying something to hold me over just to buy something I really wanted a short period of time later. Any switcher you buy is going to be several hundred dollars..

Hope this helps.
