I have one strung up low G I'd probably be willing to part with. It's a good uke; it doesn't sound quite as lush as Kanile'a super concert, but I think you'll be pleased with your purchase if you end up buying one new.
How much are you willing to spend? If we're in the same ballpark, I could take some pictures and make a recording tonight.
Also, I have a Yamaha THR5A amp, 1/4" cable, etc. if you're interested.
