Putting the usual argument's aside regarding on-line vs brick and mortar which have been well covered elsewhere, I was wondering what the experience has been for those who have purchased a Sammy DLP or any other big screen set on-line? Does it make a difference if the on-line retailer is an authorized dealer such as Crutchfield, On-line or TVAuthority? Just wondering as I am seeing a huge drop in prices in a few models that CC and BB will not match.
