i'm after a projector been offer a optoma hd800 for around £900 but have noticed this is the same price as new optoma hd20. I know the optoma hd800 is an older model now i think it's been discontinued but was a £1200 model, is it the case that the new optoma hd20 is as good or better just the price of the technology as come down over the years. would love to know if anyone as seen these 2 projectors working so could give me some light on what would be the better buy. many thanx for reading
