panny 42" 700u (the one i got)....amazon has it for $1399 last I knew with free shipping and no tax
i bought mine from invision displays for $1500 shipped no tax two months back, it might be even cheaper than amazon
its been widely picked as the best tv at its size, and also is the tv that holds its resolution the best with moving pictures (comparison the best: the 700u plasma held 880 out of 1080, where as the best lcd the sony xbr4 only held 600 out of 1080)
plasma's still offer better size per inch in price and picture quality, just keep settings low for the first 100-200 hours and you'll be good to go, panny and pioneer are the best plasma's, id stay away from anyone else as they tend to have actual burn-in or more prominent image retention problems
to compare, i played super paper mario (a bright game) for about 6 hours straight one night on my tv after "breaking it in" and didnt even notice any IR (a stuck image that will disappear after watching some other moving content)
two things will hold true no matter what though when it comes to tv's (not talking PQ really here either), bigger is better you'll understand when you don't get the smaller tv(s) you are considering and that you get what you pay for (get a cheap brand expect a worse picture, shit customer support, and problems with the product itself)
three companies known to be good with customer service and quality in every aspect are panasonic, pioneer and sony, tv's, specifically HDTV's are one area where the big boys still hold their pull
check avsforum.com for opinions from people who own tv's there, people there own all ranges of hdtv's, just watch out as like anywhere they have idiot fanboys who jump into threads to bitch
dont impulse buy either....RESEARCH!
