I have a samsung 1080p DLP which I've had for over two years and I love it. There are some disadvantages and advantages though:
Disadvantage: the viewing angles, particularly the up/down ones, are much worse than a direct display such as LCD. This is a disadvantage, for example, when playing Wii fit from too close to the TV.
Advantage: the contrast ratio and black levels are far better than LCD. LCDs often state "dynamic" contrast ratio, which is useless.
These are the two biggest deals for me, although there are a variety of other advantages and disadvantages. LCDs have a more pronounced screen door effect, DLPs have the silk-screen effect. My recommendation is to go to the store and actually view them as you would normally. Keep in mind that you should try to reproduce the viewing angles you'd use in your house, etc..
cables: be sure to buy them in advance from a place like monoprice. Do not buy them from best buy or you will be complete ripped off. Also, if you get a DLP they'll try to push the warranty on you and tell you your bulb will burn out. The bulb will last you 2-3 years and costs less than $150 on the Internet.
Be sure to get component cables for Wii/PS2 and HDMI cables for anything you have that can connect VIA HDMI. Buy them all from monoprice as that will be, by far, the cheapest place for you to get good quality cables.
