Buying late model Samsung DLP rear projection TV?


Is it worth considering buying a late model slim Samsung DLP rear projection TV on the used market? Flat panel TVs are coming down in price, but a used DLP is still cheaper. I am aware that a new bulb will cost $150.

I've always found the off axis picture quality of DLP's and other rear projection TV's to be the biggest drawback.
Off axis viewing was a much bigger issue with early generation RPTVs. For me available screen size, great picture, visibility in high daylight conditions not to mention affordability were the important attributes leading to purchase of an LED-based DLP rear projector. Off axis viewing hasn't been an issue at all in our great room.
I have the Samsung HL67A750 and love it.

It isn't as bright as flat-panel LEDs, but phenomenal nonetheless.
