Which "Kind of Blue". I'm so confused

So last night I'm playing DJ ad my wife asks if we have any Miles Davis. We don't. We're not big jazz fans. Tell her I know I've seen some of Mile's recordings raved about on Audiogon and I'll do some home work and add some to our collection.

So, seems if I get one album Kind of Blue is a no-brainer. I got to Secondspin.com where i have some credit and see 3 CD's. 1959. 1959 remastered w/bonus tracks. And one (3x the money) 1993

I'm so confused. What's the recommendation?
