My source is Comcast cable. I do not have HD yet, as my current tv does not support HD.

I alpos plan to buy a blu-ray player when I buy the new TV to take advantage of the better picture provided by blue-ray......
9 Feet away from a 60ST50: PQ with (most) Blu-ray or HDDVD disks is Wonderful. (Some transfers are simply not up to snuff...)
HOWEVER: PQ with "HD TV" or "Upconverted" SD DVDs ranges from "Ugh" to "Very Good" - with MOST programs falling into a middle ground of "Yes, there are a lot of visible flaws - but look how great a blu-ray looks!"
At 9 feet, a 60" panel will Readily Reveal whatever FLAWS are inherent in the source: and the majority of "HD TV" programming falls at least somewhat short of "HD."
And, of course, Upconverted SD DVDs are merely 480 Blown Up to fit the screen. These actually look Pretty Darn Good on our 50" plasma - at between 9 & 11 feet - but find many of them rather Jarring on the 60" at 9ft.
Fortunately, we have a secondary seating position that is roughly 12 feet back, and that makes all the difference (barring, again, a poor transfer).
Your EYES may differ: my wife is a musician, and comments (& sometimes complains....) about Audio bits that I simply do not "hear."
OTOH, I will often be ready to turn a program (or SD DVD) OFF in disgust because of the PQ, and she will ask "What's wrong with it.??"
Coming from ALL SD, you might not have a problem with cable or upconverted SD DVDs. Just as someone coming from VHS would be WOWED by SD DVDs!
