I've got a Panasonic 5 disc (CV-51), and am very pleased with it, though it doesn't have some of the features that the newer ones have. Really like my Panasonic VCR, as well. Good products at reasonable prices. Found this at the epinions link Execution Style posted:

Bought my parents a combo VCR/DVD player for Christmas. It's a Sanyo, and I don't know anything about them quality-wise, but it has alot of features, and a well-laid out remote (the features are so similar on all the different brands that I actually bought it because it had the most user-friendly remote). Ran $204 after tax.
btw, I'm a big fan of harman kardon if you've got the bucks-I'm sure they make DVD players, now, but haven't shopped around. If money grew on trees, I'd have all h/k stuff.
I've had a h/k receiver and 5 disc CD changer for 11 years...ha, $1300 for a top opening changer and 2 channel receiver back then

, and both work like they did when new. h/ks are nice, classy looking, well-finished pieces, built like a rock, and the listed specs (specifically power and distortion) are highly underrated.
