I bought the 732 last 1/23/12, delivered the next day. It was $2225 while the 632 could be had for $1849. I choose the 732 because I wanted the extra brightness the Quattron (4th pixel gives me). I checked them out side by side at Costco (before buying at ABC warehouse), and the picture quality looked the same. I was able to put them both in the movie mode. Love the set, only see clouds if I crank the setup and only on "white sky like" scenes. I had a Samsung 71 DLP, and it had a good picture, but wasn't as easy to see in bright daylight, and doesn't have the color pop.
