Are you set on that size? Costco has some awesome deals on the Vizio TVs and people seem to go crazy for them and the company.
No - not set on size.
would like at least 37"
Are you set on a budget? I think the most important thing to do would be to decide on a budget, and then find the best TV to fit that budget. Along those lines, factor in an extended warranty into your budget. It WILL pay for itself.
Are you set on the technology? DLP/LCD/Plasma etc.
Really just starting the search. I think LCD is the way to go, but could be changed on that.
Under $1000...
Little concerned about energy usage with Plasma.
The LCD uses less energy, however, keep in mind, the energy usage is based on the "Content". LCD backlights are generally constantly "ON", and are always consuming power, even when the scene you are watching is dark. Plasma uses tiny fluorescent type bulbs, which only turn "On" when needed, based on the scene you are watching. The energy debate is controversial as it is possible your plasma may use less power during darker scenes vs. an lcd. Also, because lcd lamps are always on, the black levels cannot possibly be true, because the lcd chips are "twisting" closed to dampen out the backlight, leaving small gaps for light to come thru, (Like a bathroom door, you can tell you left the light on around the door trim) Most plasma's have True contrast ratings of over 10,000-15,000 shades between black and white, as the bulbs can "vary" intensity, unlike lcd, which cannot generally produce deep black.(Most LCD's have a True contrast of about 2,000-5000 shades) All said and done, don't buy your new tv because it uses less energy, as most new TV's use at least half the energy of the old "CRT" type tv's anyhow. Also, plasma's do not have a refresh which means they don't have a "lag" in the image when watching fast moving sports or movies. Good luck.
1. Extended warranties are generally rip-offs. As Consumer Reports says, you'll most likely pay more for the warranty than any repairs. Plus, if there is going to be a problem with the TV, it usually shows up in the first 30 days. TV's are known to either break quickly, or last forever. I know people here will disagree, as there are ALWAYS exceptions to this.

2. If you're comfortable, buy online. You'll almost always find a better deal than retail. (Unless retail is having a crazy sale.) I recommend Newegg.com. I've used them many times in the past and they've been great.
I have a DLP. 60" Sony. It's about 2.5 years old. It is the 1st generation 1080p sets.
I'm going to upgrade to projector in 1-2 years.
I would not recommend that. I've been using a projector set up for the last 8 years. I've had 3 different ones in that time and after buying my 50" Samsung, the picture quality doesn't even compare. Plus the cost of replacing the bulbs every year or two (depending on your usage of course).
What about Vizio's?
