Costco is selling a brand of LCD HDTVs called Vizio at prices well below those of equivalently sized Samsungs, Sharps & Sonys.
They are reported to have great quaility pictures.
With Costco, you can return for full refund if not satisfied.
I've heard about that business of SD on a HDTV being not good.
Have they done a side-by-side with a top quality, equivalent SD and HDTV of the same size and with both tuned to the same
No, because it's not possible.
So what they end up doing is comparing between an HD channel and an SD channel on the same HDTV and report their dissappointments in the SD picture quality.
Outside of that, the reports are quite accurate.
