Which cd changer to buy

I need a new changer to replace my failing Marantz. I really want the Sony SCD 555ES but am having a hard time finding one to buy. They sell very quickly here. Anyway, would the Sony SCD 222 going to be noticably 'worse' than the 555? What about the 333; That has good press but older. Are the newer models that much better?

SACD is not a deal breaker for me, but a nice feature. At this point I can only use 2 channel so the 5.1 channel is also negotiable. I'm in a hurry to get a replacement, so opinions are appreciated.

I'd go Denon, myself. Great bang for the buck. My DCM-460 still sounds great.
