They come out with a Prince model! 

Actually, years ago, i traded my drum machine for one. Glad i did. Forced me to find a real drummer and i learned i don't like Ukelele after all. True story.
I scored a 1968 Gibson Uke for $10 at a garage sale. It's worth about $600 or more...
Now I wanna learn to play Train's "Soul Sister..."
Actually, what you do is move the strings around a bit and it will facilitate tuning to low G.
You move the C string to where the G string is. You move the E string to where the C string was. You move the G string to where the E string was. You leave the A string alone.
That gives you the thickest string for the low G (if it is wound, so much the better) and rearranges the rest of your strings appropriate to their relative thickness. This is known as the Brudda IZ tuning. Alternatively, you can just get another C string and replace the G string with it.
