I've been thinking about getting an instrument that is easier to travel with than my banjo or gut bucket is, and really like the sounds of banjo ukes, and as a close second regular ukes. However, I also tend to like instruments that are tuned lower than the Soprano Uke.

So...

Do banjo ukes only come in similar size/tuning to Soprano ukeleles? Did anyone ever make them to replicate a Tenor or Baritone ukelele?

Also, What are the differences between a Soprano, Concert, Tenor, and Baritone Uke? Has each traditionally been used for a different type of music or style? Do you play them differently?

Last, are there any good banjo uke makers today? Is it still possible to find a good used banjo, tenor, or baritone uke? What should I look for to make sure that I'm not getting taken advantage of?

Thanks
