But how do I get a good-quality player w/o 6 unnecessary analog jacks on the back?

The presence of those jacks does not affect the quality of the player's digital output, and they don't really increase the price of the player much. I wouldn't consider that an issue. If you're going to use the digital out, just ignore that they exist.

When choosing a DVD player, it's more important to look for one that doesn't have the common de-interlacing bugs.
