i just got a sony KDF-E55A20 55" LCD rear projection and man let me tell you i LOVE it! .. this thing is soo cool. i looked at alot of 42" and 50" from Hitachi and others. but this is by far the best picture and user interface (onscreen) that i know of. im using my PC on it as a monitor ( up-to-date graphics card w/ HDTV ) and will have the XBOX 360 on it as well. movies rock and so do the high-def channels i get for FREE !.. the computer chip scans your cable for any digital signals. so cool.
i do not regret getting my sony. i could never go back to anything else period.
