I might just buy a Blu-ray and keep my CA 640R (without HDMI) and let the Blu-ray player upscale my existing DVD's onto my projector but I already have the Sky HD plugged into it via HDMI so will require a switcher.
I used to use a Bandridge VSB1002 which I bought from Maplin. It only cost about £15. It has two 1080p inputs and one output, doesn't connect to the mains and is very easy to use.
It was very cheap feeling and plasticky, but what do you expect from something like that?
