What does DLP stand for and what brand did you purchase.
After reading through these websites last month, I was 100% sold on DLP TVs. If you buy one, then, as they say, it might be the last tv you ever buy because nothing wears out except the light bulb (which costs about $300 and needs to be replaced every three or four years depending on how much you watch tv). TigerDirect.com seems to have the best deals. But be careful. You want new, not reconditioned. And 1080i is not nearly as good as 1080p.
However, when my wife and I went to the dealership to take a look at them side by side with other televisions, I couldn't stand the DLP picture. So we ended up buying a Sony S-LCD tv (liquid crystal on silicon) which has a MUCH better picture than DLP, imo, but costs about twice as much (which is still only about half what you'd pay for a comparably sized plasma tv).
