Samsung HL-S5686W 56-Inch DLP HDTV

Check out the reviews at Cnet.com and decide if the difference in price between the Sony and the Samsung is worth it to you.  Further decide if you want to spend more for a 1080p (the new standard at some future date) or go with 720p/1080i which is the best broadcast available today.  Remember that the prices will continue to fall.  This model delivers excellent high definition.  I watched the Texas game last night on ABC and noticed metal flake in the helmets, condensation on the water bottles and a grasshopper on the bench.  My standard DVD's look better too.  The only problem with this TV is that I can't stop watching it :)  In conclusion:  save money online and don't pay TAX!
