Not really. Out of the 3 technologies (LCD, LED and Plasma) the LCD is by far the worst with SD broadcasts.

Only 2 technologies here. LCD and Plasma.
Normal LCD's use fluorescent tubes arranged/spaced horizontally to provide back light for the LCD panel.
LED displays use banks of LED's for back light. No major improvement apart from light "bleeding" a little less noticeable.

Yes yes localised dimming vs backlight technology... old news.
My question is how bad is a LED TV without Full HD and 50hz motionflow compared to a Full HD LCD with 80hz motion flow...?
Wow, interesting. Thanks for clearing that up. Never too old to learn.

Never seen the 2 side by side to draw a informed conclusion, but i would say they are much of the sameness. I personally won't go for LCD tech. but rather a full HD plasma, as they display SD content better. And for Blu-Ray/games, you still have full HD resolution. Best of both worlds really.
Why? What's wrong with LEDs above 50"?
Sorry, my mind was working ahead of me there. I was doing the comparison between Plasma and LCD, not LED and LCD.
Does Samsung even make a non-full HD LED? ("full HD" and "LED", two big buzz words these days, didn't think they'd bother with LED without the other one) ... or are we talking about screens smaller than 40" here?
...anyway, do yourself a favour and just go for plasma, fullHD or HD Ready, doesn't really matter .... Panasonic if you can afford.

Well thats dependant on if its side-lit or back-lit.
Side lit LED makes the tv thin and gives no improvement to picture other than the backlight bleeding.
back-lit makes quite a big difference as the LED's behind the image can be turned on or off or even run at different colours thereby enhancing blacks and normal colours. Its all marketing hype at the moment calling them LED tv's because they are still LCD with different lighting as you correctly put. The only problem is that we only get side-lit here at the moment so people are effectively paying more than double for the same thing with different lights in it. Oh how awesome marketing can be!
So what is different about plasma that allows it to achieve this?
It's not a technical limitation issue more than a cost reduction issue.
LCD and plasma both have fixed-pixel panels so theoretically, they should fair equally when it comes to SD content. The difference is really in the image processing (scaling). Plasma TVs generally have better quality scalers while LCD, due to the already-expensive technology, tend to use cheaper scalers to keep down the overall cost.
But then, a great scaler isn't necessarily the be-all-and-end-all of good SD display, as can be seen in quite a few LCD panels that use identical scalers to the top-end plasmas, yet still fair somewhat worse in this arena. It needs to be implemented properly as well, not just slapped in.
However, the LCD technology itself is more than capable of displaying incredible SD content which can be seen if you run the feed to your PC first and let that do the scaling for you before passing the signal off to the TV.

If your planning on buying a small 32" go 720 or HD ready. You won't notice the benefit of Full HD on that size except if you are sitting less than 1 meter away from the TV. Depending on the room size, for that money, I'd rather go with a bigger 42" HD ready Samsung or LG plasma for R6.5k. New flat panel TV's tend to shrink very fast.
