RoyalTek RPJ-2000 Pico Projector and a usb-to-vga (sisusb) card work perfectly well

the projector is 640x480 , Osram’s LED that last over 20000 hours , 3M optical engine (second version) as its projection source = same image quality than 3M MPro150 , fanless , vga and composite input , 14 lumens : you need (almost) black room like in a cinema , 65” maximal projection screen size , - 100-240V 50/60Hz 0.5A or 5V 2A

I paid 219 Euro for mine

you may have problems watching movies due to the usb-to-vga card = the bandwidth is not that good . For example with my olpc XO-1 I can run quake2 fullscreen only at 400x300 ( with no latency )

combined with an ipod you can watch movies at DVD quality
