I bought a cheap point and shoot camera from them and it was okay. But I wouldn't buy a $1600 TV from them. I lived in NYC and visited places like Abe's of Maine (they are actually in Coney Island, Brooklyn, NY), B&H Photo (West Side of Manhattan) etc. While it's amazing how they've set those places up (conveyer belts in the store to get product to the customers), they aren't really online customer oriented shops. You could find some oddball stuff in them. Weird lenses, filters, old radio parts. Even some grey market items. But I would not buy a TV there.
I'd pay a little extra to get it from someplace reputable.
And yes, that's their racket. Several online places like All Time TVs etc. do that. They advertise a low price, them call you to complain about extra costs. Then if you don't fall for it they will be out of stock (often holding your money) until you finally cave in and pay the extra.
That's why Best Buy/Amazon/Pauls TV etc. usually won't price match them.
You'd have better luck playing Best Buy against Paul's and see if you can get them to compete for your business.
Personal opinion of course. Hope it works out for you in the end. Good luck and enjoy your new TV when you get it!
