I bought a 300 disc DVD changer from them and I didn't have any problems. It also says on their site that they don't sell used, reconditioned, or refurbished stuff so that's cool too. Anyway that's a good sub and the price is really good too. You can get the same one at Amazon for the same price. Etronics probably has better shipping prices though.
They also have the really nice Yamaha NS-333 Two-Way Bookshelf Speakers for only $130 a pair!
