Think of it this way- you spent a couple of thousand dollars on an HDTV, and now you want to know if you should spend another $200 to be able to see what sets your $3000 TV apart from a $1000 TV.
Getting an HD receiver was a no brainer for me, and my TV isn't even HD.
To put it another way, I hate baseball, but I have watched several games because they were in HD. The picture quality; the Dolby Digital sound................
To put it yet another way- GET OFF YOUR WALLET!
