Aloha Heather,
a second vote for musicteacher 2010 from me - I'm a beginner too, got my first uke about five weeks ago, and even though Aldrine's tutorials are amazing and provide cool tips and wonderful songs I find them mostly doo difficult to learn.
But I've got no experience at all with any instruments...
I don't want to tell bad things about Aldrine's tutorials, in fact he's just an amazing uke player, I like his way to make the videos, he's explaining very good, but the arrangements of songs are (for me !) often too complicated - I think I'll get there one day and use all the great ressources he leaves here, but for a start I tried to keep it simple and found my personal success with musicteacher 2010 - lots of really simple songs, very well explained, and shown and mostly just strumming, without complicated strum patterns....
I also recommend the Ukulele Boot Camp - because it teaches you a lots of chords in no time...
Have fun with your Uke !
