I have an older-edition Sony 5-disc changer (circa 2002, which probably means it's an antique by now), and I really like it. I've never heard a discouraging word about the later Sony 5-diskers that have come out. What I like most about my sony is that I can easily mark the exact frame in each disc where I want to start, even if it's in the middle of a chapter (for instance, starting right at the beginning of the ultra-hi-impact portion of MIC), and the Sony "remembers" that point for several days.
