Please help me decide.

I was about to make a purchase when the 120hz thing popped up. None of the set's I wanted had the feature. The set I have in the bedroom is 25 years old and the 36" would take it's place.
If I get the 40", I could sell the 36" in a year or two and put that money towards a 57" DLP(unless no one here thinks DLP's are competitive).

Take a look at Banyan Electronics:

I have the XBR WEGA 16X9 1080I unit thaat is 34in wide, its deep, heavy but it smokes any picture out there at this point in time, if it is a model like mine and hi def I would grab it.......my unit was $2500 almost 5 yrs ago and still as beautiful as ever, I watch movies on our Projector but everything else on the Sony as its that good.

It's the 40XBR800. I originally wanted this model, but was too big to fit through the door.

I didn't know Sony made 40" CRT TV. I had a 32" XBR CRT and it was just a huge pain in the butt when I was moving. I eventually sold it on craigslist, but it was not easy to sell due to the weight. One of my friend had 36" XBR, which I thought was the largest CRT Sony ever made until I saw this thread. He practially gave it away just last year as nobody wanted it. For $500 it may look like a good deal but it's going to be a major 200lbs+ pain in a couple of years when you want to get rid of it.
