Hey - Hello,
I started playing a year ago - and I'm hooked, they are just plain fun to play.
I started with a Lanakai tenor, then bought a soprano Bushman (both sound good) and then find of the century - I went to a second-hand store and found an old (no sticker on the headstock so it is 1930 or older) CF Martin style 2 ukulele! It had a few cracks which spruce tree music (in Madison) fixed up just fine. Got my Bushman there to - great place.
I find myself playing the soprano's instead of the tenor. Was so much fun my brother(who is much more musically inclined then I) started playing too.
If you are just starting I strongly recommend forking up a few extra dollars and buying a decent one. Lanakai and Bushman are both good IMHO.
One thing of note if you are new to the uke, they do go out of tune fast but - in my experience after playing for a while they hold their tuning longer - I don't know if the strings stretch out or something. Also, if there is a little screw in the tunner peg make sure it is snug.
Here are a couple of sites that I really like:
http://ukulele-lessons.com/
Dorthy Muncy - very nice always answered my e-mail questions and each song includes an mp3 of her playing, I love this style of playing.
Also, http://www.doctoruke.com/ lots of great songs and some have music clips.
People are always suprised to hear me play (not that I'm a virtuoso!)- they say "I thought ukulele's were just toys" Anyone in doubt of that should watch Jake on UTube playing "while my guitar gently weeps"
Oh, one more thing...this site is absolutely fabulous!
