Marantz cd players


Looking for some advice on a possible purchase I’m planning. 
I have been presented with a few good deals on a couple of different Marantz cd players.
1. Is a Marantz sa-10
2. Is a Marantz ki-ruby 
3 is a Marantz sa-30
Looking for the pros and cons and the benefits of each one over the other. 
I am looking at the Marantz brand because I am Familiar with the brand and something I have always had good luck with. 
Thanks for the help/advice

I fell in love with the ruby upon first listen. I did no comparisons or shopping; I just bought it. I don’t know if the other players mentioned have this, but I like that the ruby has coax and optical inputs and it’s own volume control.
