I've been toying with the idea of getting an SACD player. What should I be looking for?

I went into Best Buy last night and the only SACD player that they had was a Sony DVD player that was SACD compatible. Is this generally how SACD players are sold...doubling as DVD players? Or can I buy a separate SACD component? I don't want to replace our existing DVD player as it doubles as my CD player and is a 5-disk carousel...unless I can get a comparable machine (i.e. 5-disk) that is also SACD. Cost will also be a huge deciding factor here. The Sony DVD player was $200. That's about my limit. If I have to spend more than that, I'm not buying it right now.

What do I need to know as I contemplate this purchase?
