ganja_25,
From another N.Mexican, sign up for the 722--you will love it. Then get an EHD or several and sign up once for that. 1TB now about $110--cheaper than any of my 750GB and one 1TB. I have about 4.5 TB total good for 800 mixed (60% HD wish TCM was in HD or had Voom back although it helps that we have move premium HD) movies plus several series, 98% IMDb>7.5. It cost more when I bought them.
If you can go with the A750 from Samsung. I have the HTL5687SX, with the big advantage of LED drivers for the DLP. This means you don't replace the arc bulb every 4000-6000 hours and the set is nearly instant on and no color wheel to make noise. I had a HLS5687 (bulb >$100) but had some problems and they replaced at an upgrade price with the HLT. I have it on many hours of the day and would have easily worn out the bulb more than say twice a year, had I still had it. Today's price is much better than 2 years ago but glad I didn't wait.
And if you have the room and $$ go for a 50" or bigger as you want to be closer than you may think to get the real wide screen effect, e.g., say at 8-10' for the 56".

P.S. poke around at AVS for a good starter set of setting--you do not want the showroom brightness, probably movie mode. -K
