We bought the 46" Samsung UN46F6800 from B&H at the beginning of the year. Packaging was as they received it from Samsung plus additional edge and corner reinforcement. Sadly the TV had a 3 pixel wide line right down the middle. Except for the latter we were happy with its features and picture quality, so we phoned B&H first and got an RMA but tried to get it repaired by Samsung hoping that would save us having to repackage it and send it back.
Unfortunately Samsung really messed us around because they didn't have the parts in stock. FWIW, they don't repair anything, they just replace all the necessary electronics. Because our 30 day return option was running out, we opted to return it and got the 47" Sony KDL-W802A for a few dollars more.
We had the new TV up and running less than a week after we dropped off the Samsung at UPS. No hassles plus prompt and excellent customer service. No wonder they have such an outstanding reputation and are the primary source for most professional photographers.
As for the new TV, less elegant and useful remote compared to the Samsung, but comparable picture quality with a noticeably wider viewing angle.
Highly recommended for those who want a retailer to stand behind the products they sell, but as mentioned above, neither of these places are geared for looky-loos or those who don't know what they want.
