Swampwalker, I think the concave problem with flat screens you have noticed is often if not more often true. I suspect it's due to quality control issues that are endemic to the flat screens. I have noticed some flat screens don't do this, but more often than not they do.
Recommendations for a nice direct view set
I am in need of advice for the purchase of a new direct view tv for my smallish HT. I am looking in the range of 35-36", and have always had a preference for Sony products. What is the real bargain in sets of this size at the moment? I need at least one set of component-ins. I'd like to keep it under $1500. Thanks!
