samsung LN52A650 vs HL67A750

[supaflyz]

Can I ask you guys about the picture quality of this tv compare to the samsung LN52A650 LCD? I use to have a 70 inch sony xbr rear projection tv. The picture quality was astounding on blu ray. The only back fall was its weight and it can only go up to 720p. So I manage to sell it and bought the samsung 52 inch. The picture quality was a little bit better, plus it has 4 hdmi inputs. However, I miss the big screen size to watch sports. Any of you guys that is lucky enough to own these two television could give me some opinions? I have 2 weeks left to return my tv. I tried to go to Frys to check the picture quality, but how Fry's set up the tvs make them look horrible. All the tv had bad picture quality. I had to go home and hook my blu ray player to my 650 to get the best picture. Its like frys are playing dvds not blu ray. The HL67 inch right now is about the same price I can get for the 650. The 16 inches the HL67 gives is tempting. Are the picture the same or on par with the 650?
