I do not have the DV-363, but at 99USD from Walmart at http://tinyurl.com/q1dj it seems like a great deal.
I have played with the Pioneer and Panasonic models when and where I could and from memory, the Pioneer seemed to beat the Panasonic in a simple procedure. Power off, press the eject button, pop in a DVD and press the play button. That's all of two button presses and the time to start the movie was many seconds faster on the Pioneer.
A nagging issue is whether you find such models in stock about your part of the world.
It's just my opinion that I'd get the Pioneer because of playing with such in the showrooms and that I'm very pleased with the DV-250 at home.
I've Narrowed it down to 2 dvd players and need opinions. The pioneer DV-363-K http://www.pioneerelectronics.com/pna/product/detail/0,,2076_15020669_35372,00.html or the Panasonic DVD-S55S http://catalog2.panasonic.com/webapp/wcs/stores/servlet/ModelDetail?storeId=11251&catalogId=11005&itemId=63318&catGroupId=11059&modelNo=DVD-S55S&surfModel=DVD-S55S. Opinions on which is better is appreciated.
