Well, I am typing this post on a 61A750, the little brother of the tv mentioned above. I sold the CRT for a couple of hundred, plus a few other items to a college student, went out and picked this up after my wife got home from work. Ah, the joys of 36 month financing. And I managed to fit the other DLP most of the way into the built in, it sticks out a couple of inches, the width of the frame basically, which doesn't look too bad. However, if I can sell it for a decent price we will and get a smaller tv for there.
Anyway, so far so good with the new LED DLP. I haven't really done much for calibration yet, but it looks great, the blacks are much blacker than the older dlp. No geometry problems that I've noticed. HD local channels look fantastic, as does the 360 and pc gaming. So far the only thing I'm not thrilled with is watching dvds from the pc. Haven't figured out why yet or how to improve it.
Now I'll need to figure what the most efficient way is to move to blu ray (have an older HK 235).
For the money and size, I think these tv's are hard to beat, especially with no bulb to replace. I just hope the LED's last since I didn't buy an extend warranty.
Now, I just got to figure out how to deal with this really tiny text that I can barely read from the couch...
