Samsung LN40B750

i have the ln40a650 and the Samsung LN40B750 and i'm starting to wonder why i pay so much more than a more economical lcd set, is it the 120 or 240 hz? , i'm not so sold on it anymore, and yes i have the 100 dollar hdmi cables, the 120 and 240 hz is noticeable in film content but, for regular viewing it is inconsistent at best, as a matter of fact, the whole HD experience for viewing regular programming is unstable, so why keep paying so much more? my blu ray player looks great on this set, though i bet it would look good on any lcd or plasma, expensive or not, and as for the widgets, ho hum, i have many other options available for weather, stocks or useless information, the makers of these more expensive sets keep selling us on these new ideas, but, is it worth it? i'm gonna have to say no, at least not yet anyway. it's a very good set, i just think overpriced a bit
