I am in the process of searching for a new lcd tv and with new models coming out at this time of year i wanted others opinions. but basically out of all the major lcd manufacturers ive narrowed it down to sony or samsung.. kinda leaning towards samsung. i came across the LN-S4051D which looks like a really nice tv, but last night when i was browsing in future shop and best buy i came across the samsung LN-S4692D which was an "exclusive" and had a 5000:1 contrast ratio instead of 4000:1. so today i did some more researcing on samsungs website and found an even newer model which has a 6000:1 contrast ratio... LN-S4096D. so my question is, is it worth the extra money to get the 92D OR 96D? or should i stick with the 51d? i dont know much about the sony bravia tvs... but they seem a bit overpriced to me. one of the people at best buy told me sony was the ultimate best because their tvs have an "iris control" which produces better blacks since it totally shuts out the pixel when producing blacks so the fluorescent backlight wont seep through. so i need some opinions and advice to help make a decision. and of course if i happened to miss any other good lcd tvs out there... please let me know.
