Hi,
In the end I bought a Vogel's Universal EPC4010 and I'm very pleased with it. I got it from a place in Germany via ebay at a pretty good discount. The store is here:

However the guy told me that he was going to have to raise his prices due to pressure from his supplier.
For installation I found a local electrician who did a really good job (inlcuding fitting new wall lights to replace a ceiling light), although I did all the measuring up of where to site the projector to get it central and correct screen size.
Good luck!
