Ukuleles are fun :-). I've tried playing a lot of different stringed instruments over the years, but never got as far as fast as with the uke. Armed with a ukulele, a chord chart, and a computer to google song tabs, you can be strumming songs you know within an hour. Try it - google "[song name] chords" (without the quotes). You will almost certainly find a listing of that song's lyrics along with it's chords. It may be on a guitar site, but that doesn't matter - just play the same letter chords from your ukulele chord chart, and there you have it!
I built my first stringed instruments in the mid '70s, and have been concentrating on ukuleles (and banjo ukuleles) for the past few years. I do good quality hand made ukes for reasonable prices; not much "bling" but great sound, set-up and "playability". Please click here to look at ukes I've made that are for sale.
