Update: This may help (http://www.projectors.co.uk/) And to clarify what I will be looking for: a big image from a short throw distance. (Ultra short throw projectors) (also more here)
Update 2: This one seems to be just about perfect - will worry about price later (most likely out of budget).
My plan is to have a projector within the table (rough plan/model coming soon) The problem I may face is there may not be enough depth in the table for the projector to fill the entire surface of the table. Need to look at the technical details of the projectors to get info. I imagine this post will update over time and the following (cheaper) projectors may not be 'eligible' for the table.
HD Projector for games consoles/laptops etc
