Can anyone explain the differences between the 6 and 7 Series Samsungs? Looking online, I've found the 40" 7 Series for about $50 cheaper than the 6 Series at the same store. I can't imagine there not being upgrades on the 7 Series. So, for less money, I don't know why someone would go for the 6 Series.

Well, I think the 550 is just fine. The only difference between that and the 650 is one ms of response time which is negligible, and it was 120hz ... but the 550 was just fine at 60hz. So, why not save more money and go for that? A lot of peopel say great things about it.

I'm about to buy a 52750 so i have been reading alot. Here it is but i just copy and pasted it.

Differences between the LNxxA650 and LNxxA750:
750 has an integrated woofer
16-bit processor vs. 12-bit in 650 (10-bit panel in both)
750 has DLNA features (can stream audio/video/etc. over a home network)
750 can play video off of DLNA/USB flash drive. 650 limited to images/audio
750 comes with 1GB internal flash memory pre-loaded with HD pictures, games, recipes, and a few other things
750's controls on the bezel have a red backlight. 650's controls have no backlight
750 has a square bezel compared to the 650's rounded bezel
750 has a square stand compared to the 650's oval stand
750 stand does not swivel (contrary to Samsung's literature)

go with the 750. I'm getting a 52750 for 2449.99 from Bestbuy.

If you wait a day or two. I can give you my 8% of CC code or email you it and you can take it to bestbuy and try to have them match CC like me? LMK
