I have the Sony CDP 450 (400 disc) daisy changed to the Sony 230 (200 disc). I went with the older 450, as opposed to the 455 because the 455 doesn't let you view the material you enter on the television. I figure that if you're going to place more than 25 discs or so in a machine, you'll need to be able to scroll through a larger screen than the little box they give you on the player.
I got mine in eBay (buyer beware, of course), but am perfectly happy with mine. I daisy chained the two players so that I coudl avoid having any gaps in music when I play teh discs on random. For example, we threw a party at the new hosue this weekend. I had a few of my friends pick as many cds as they like - I threw them in the machine, and bingo - I had continuous, random music for the whole party. It's nice to be able to do taht and literalyl not have to worry abotu music for the evening, and not suffer gaps in between songs.
The 455 does have mp3 playability and has some more options as far as entering song titles and artist names etc than the 450. But, for my needs, the 450 did a great job.
Note that you can't find the 450 really anymore at "real" stores because its been out of production for some time. That means that, mostly, the 455 is going to be the player of choice - without options...
Sony, I believe, is the only manufacturer making 400 disc players, but I could be wrong. I think the soudn quality is fine, and I haven't had any mechanical problems yet. I still haven't input the cd titles etc. into the system. I'm waiting to do this in an organized, systematic fashion....
Anyway - the long and the short is this - consider doing the 450 or the 455. Also consider strongly daisy chaining it with another system so as to eliminate the delay.
