The only LD player I've ever owned is the one I still have, Pioneer CLD-3070.

Is there a site or page somewhere that compares the players?

This site has a lot of good info about Lds and Ld players - scroll about halfway down on this page: http://www.mindspring.com/~laserguru/askjosh.htm#hardware
and Josh gives a rundown on what are generally considered to be the best players. Elsewhere on the same page, he mentions some of the players to avoid.

I based the purchase of my cld-d703 based on his recommentation, and I'm very happy with it. I don't think you can go wrong with any of the players on that list.

The rest of the site is informative, as well. Use the "chapter listing" at the bottom of the page to navigate the site.

This site is also useful for in-depth tech specs and photos of all known Ld models:
