Lin- Sounds like a great opportunity to test the waters. A nearby library here is offering ukes on loan, and there are similar offerings at other libraries in various parts of the US. Schools have taken up the uke banner as well, using them in school music programs, and uke groups and clubs are showing up in many towns worldwide. http://ukulelehunt.com/2010/03/10/ukulele-clubs-and-groups/

Have fun!
