Money is sort of a factor and i wanted to know is it worth it to get an LCD for so much more for the same size than a plasma?

I will be using it to play my PS3 as well as watch lots of Bluerays! I don’t know much about TVs besides resolutions and input standards. I’m looking to spend around $600-$700, but I’d spend a little more for a good value.
What should I look for in a quality HDTV?
Is refresh rate important?
What is better, LCD or plasma? (in terms of picture and longevity)
What is the best store/site to look for TVs?
Should I wait for a sale?
Can I expect the type of TV i’m looking for to be discounted during sales season?
If so, when’s the best time to buy?
Sound quality is not a major concern and I don’t really care about picture in picture or any of those bells and whistles, I’m mainly looking for something that will look good and not die out in a year.
Thanks for the help!
