I have a Big Island concert that I love. When I first got it I thought it sounded a little thin but it has since really grown on me. I got mine from MGM and it plays great. I liked it enough to buy myself a tenor (which should arrive on Wednesday!!!!!!!).
To add to John's post, I also have a Mele tenor (thanks again John!) and I love it as well. It's got a really thin neck which took a little getting used to but it sounds great. I think you would be happy with either of these ukes.
