Welcome Megan, listen to Sheree the Wise, Technical Forum will give you all the answers you'll need!
But I can already tell you that personally I'd choose CAVS only if I had Super CDG's. I don't have those and since they're already old technology I'd stick to the cheaper models for playing discs! I mean why buy Super CDG's when you can create your own library on a laptop from the CDG's that you already have. Good choice as a basic desktop player for example would be RJtech RJ-4100 or RJ-4200.
