May be a bit of a delayed reply to your posting:
I have a JVC HD-P61R1U, bought new from Tiger Direct in 2006. Still going strong with great brightness, color and sound! It's outlasted several large screen 42" and 47" units since then! I've never had to service it and the bulb is still as bright as ever!
The fan stays on for maybe a minute after switching the unit off. I've had numerous power blips with only a minimal surge protector. I think I lost HDMI #2 connector somewhere along the way, but that's the only issue to date! Pretty impressive reliability if you ask me!
