LED based pico projectors are cheap and robust. They make an interesting basis for table-top projection, and here we explore their use at Newspeak House and for the Worldscape installation.
I've been using the ASUS S1 for a couple of years and interestingly the price has remained roughly the same - pcworld.co.uk 
Currently there look to be a couple of interesting options. Prices below are in £:
514 AAXA M6 (1,200 lumen) 582 ASUS BM1R (900 lumen) 558 Vivitek Qumi Q6 (800 lumens) 300 Pico Genie P200 (200 lumens) 280 ASUS S1 (200 lumen - 854 x 480) 70 ELEPHAS (1500 lumen)
The ELPHAS is very odd. Incredibly cheap and bright, with a resolution comparable to the ASUS S1 (800 x 480P. 16:9 Wide Screen, Maximum 130" Projection Size) - it looks too good to be true. And probably it is.
Vivitek Qumi Q6 Grey Projector (800 ansi lumens, Wi-Fi, DLP, LED, 3D/HD)
Here is one old (trusted) bad review and one good one:
