Can someone recommend a good player by these two manufacturers? I currently own 2 Toshiba DVD players - a SD-1600 and SD-2107 (the two disc player with two trays.) I wa thinking of upgrading the player to a progressive scan model, and was wondering which players would fit the bill. Pioneer: 440 and 444 - which is better? Toshiba: 4700,4800,and 5700 which is better? How do these two manufactures compare in terms of picture and sound quality? Thanks in advance for hte posts and please offer your suggestions.
