Need help on deciding on a TV for our workout room. Keep old 'good' LCD or replace

Honestly it is your choice, but XBR2's are very nice sets. They will honestly probably have a better picture than a cheap model Vizio. It is essentially like trading in your 10 year old Lamborghini for a brand new Honda. Sure the Honda will work great, but the Lambo will always be nicer, faster, and prettier.

LCD technology has not changed much, but there is a major difference in panel qualities between brands and sets. This is why there are still massive price ranges in TVs. A $400 Vizio is going to look terrible compared to a $2000 Samsung or the like. This is why your XBR will look better overall than the Vizio.

The one things is, however, that your old XBR has CCFL lighting instead of LED lighting, which is why you have the added weight. The extra downside to CCFL lighting is that is uses a lot more power than LEDs. The difference in energy cost is about $80 a year assuming you use it for 2 hours per day average.

At the very least I would say throw the XBR2 on Craigslist or something, you could probably get a few hundred bucks for it.

I would keep it. I doubt that the XBR generates enough heat to make a noticeable difference, probably no more so than the amp in my workout room's stereo. One way to tell is to put a thermometer in the room and work out a few times with the TV on and then a few with it off.

Again, personally I would say keep it. XBR2s are great sets. The Vizio will be crap in comparison. Also, FYI the $16 a ear is estimated usage of 8 hours per WEEK which is kind of a joke for most people. Hell thats not even enough time to watch the morning and nightly news.
