What kind of Ukulele should I get?

I play guitar and I'm just looking for something that is a little easier to transport then a full sized guitar. I've been looking at Tenor and Baritone but really I'll consider any kind. I was thinking Baritone because I have a lower voice but it might be easier to use a Tenor and play it up and then sing down the octave but I don't know. What would be differences between them and things...
