Also looked at it, as others on this forum have said. It is awful. Don't touch it with a bargepole. In fact Costco's range is the worst they have had consisting of 3 Philips TV's, an out of date Sony and the only saving grace the Pioneer 50". Dropped another slip in their suggestion box to start stocking panasonics again!
BTW I have now shortlisted the Panasonic TH37PE50 (with free ES10 DVD Recorder), or the Panasonic LXD52 LCD.
