My brother just clued me in to this one: the original Plus DLP projector has now been slashed to just $1299! This is a screaming bargain, IMO. It cannot do HD, but it contains a good line doubler/deinterlacer. IMOHO, it compares very favorably to the drastically more expensive Sharp models for SD material like DVD.
If they continue this deal, I may buy one for my bedroom system!

I'd of course go with a smaller screen. One draw is that it'd be a lot easier to carry up the stairs than a huge box TV!
