Got the B550 as i think i can live without the added features of the B650. used for about 3 weeks now and the IR is quite bad in the beginning but now gradually decreasing. I am very happy with the picture at 9 feet viewing distance and only with ASTRO. still saving up for BD system. The IR is not much of an issue although have only used for about 40hours. Just dont keep bright or white lines(menu boxes, etc) long on the screen but IR washes off quite quickly. I accidentally left my laptop desktop image (HDMI) with media player running in the middle for 1 hour!! got IR but wash off after 10 minutes or so....scary but great value for $$$

there is a function called "scroll" under IR protection. Basically a black toned bar scrolling from right to left, kinda like removing stains from the screen.
