Query: Bad experience

I bought the DVPNS50P, which is a similar, if not the same, player. It worked well enough, until it stopped working, about two months after I bought it. Of course I bought the Sony, rather than a cheaper off-brand, thinking the thing frizting in two months would be less likely.So, what I'm writing about is the customer service: ridiculous. The unit qualified for "exchange" under the warranty. This means I had to bring it not to Best Buy, where I bought it, but to a UPS Store, and have it packed and shipped, at a supposed discount ($20!). Overnight service for me? Think again! So far, I've been waiting 17 days for the new unit.You would think Sony stood by their products, and that they could therefore afford to take better care of their customers when their products didn't work. This bargain basement customer service would seem to indicate Sony doesn't stand for reliability anymore!
