Perhaps if staff time/money was unlimited, that could happen <very sarcastic grin>.

Keep in mind some of the models you see @ Costco and/or Sam's club are unique to those retailers hence you won't find them reviewed online. They often only have very slight differences (some cosmetic/some features) from the standard models carried typically by Best Buy, etc. You would benefit from also perusing places like AVS forum to read actual user experiences with the various HDTV models.

That said, you might want to check out the 50" Panasonic G10 plasma. It's quite a deal IMNSHO.
