Ultra short throw projector aka Laser TV

[flatso]

We do not have a TV in the house but were thinking of buying one of these new style UST Projectors. The main appeal is that they seem to be somewhat "portable" and some may even be usable outdoors for a summer nigt garden movie night. We will be using it only for movies 1-2 times /Week.
Does anyone here have experience with these and are they recommendable?

Thanks in advance to all

Thanks to all for the useful replies! It makes sense that the proper screen is required for the UST to work properly, had always thought that there are good retractable screens to be had.
A major requirement is the portability of the system, I really do not want to have it around constantly in the living room as the children would have a constant source of temptation and distraction. I just need it for movie nights, it really need not be the last word in cinematic exoerience.
I would love some concrete recommendations.

Cheers to all
