I have the 350 and it has some appealing pros at the moment: relatively cheap at $224 on Amazon (or it was yesterday, today it's $229 through an Amazon reseller), fast load times, quiet play, small footprint, it does hold your place when you want to resume play, provides very good dvd upconversion, to my eye and according to recent CNET review in comparison to other upconverting units such as OPPO (research this last one if it's important, I'm not an expert). Cons are it doesn't decode all of the new HD Audio codecs internally and doesn't have 7 analog outs.
Sort of a sweet spot for a particular market if it isn't missing features you happen to need. You can always rent blu ray discs or buy one or two for the fun of it without going too deeply into excessive consumer spending mode.
