I don't agree with Rwwear. In the ML37/39/390 CD players the weak link is the drawer mechanism, not the laser. The drawer mechanism gets mistimed easily, and you have to follow ML's procedure to reset it. The open/close drive belt also breaks, stretches, or otherwise need replacement. ML doesn't do in-factory service any longer, but they have authorized service centers that will fix these transports. The 390S isn't that old, and uses the same parts.
I've had my ML39 for over 13 years. It's mechanically identical to the ML37. During that time the drawer was serviced once by the dealer (it was still under warranty), and I've had to reset it several times, but considering how many thousands of discs I've listened to over 13 years the drawer has been pretty good. (On the other hand, the main circuit board had to be replaced two years ago, and that was $1300. It's as good as new, but that'll be the last time I pay to fix it.)
I know ML37s are going for about $1500-1700 right now, and for that sort of money it would be a tough decision. For $1500 you can't get any other transport built like a 37, but electronics over ten years old are often cruising for a failure. I'm not one that believes transports have anything to do with CD sound, so unless you just like the quality feel of the 37 I think you're probably just wasting money.
