Jawats,
Try videogon for used projectors, although you'll mostly find new projectors offered at discounts. Technology is changing rapidly and prices are dropping quickly, so older projectors are not like older amps. The AX100U is under $2K, but you'll need to add $1-2K for a screen. If you find you need to add a flat screen TV for casual viewing, not much is lost. You'll probably soon want to upgrade from the AX100U for better resolution, but there will be a trade-off in price and brightness, or you can wait a year or two.
