DLPs look great, especially for old school games because they are essentially a high(er) tech CRT. I will tell you what I learned during the research that led me to purchase my plasma.
1) burn-in, as has already been mentioned, can occur on any current type of tv. newer tvs have built in counter-measures for this, and it isn't the inevitable pitfall that you hear about.
2) brightness loss (another alleged symptom of plasma tvs) over time also occurs with all current types of tvs. At 6 hours of viewing a day, it will take at least 10 years to have a noticable loss of picture quality (and by then you'll probably want and be able to afford the next wave of display technology)
3) When it comes to contrast, nothing can touch plasma. black levels are better also, though lcd and dlp are closing the gap.
Necro, my best advice is to always look at the native resolution of the TV. if you go with the highest progressive scan possible, (ideally 1080p, which isn't found on any42 inch or smaller tvs i have seen), and look at the aspect ratios available (most are 16:9 natively but can stretch to full screen, which looks terrible as others have said, but some tvs offer still other options for different input signals) look for an optional aspect ratio that is somewhere near 3:2 I believe that is what the turbo cranks out(?) I hope that helps.
