I've always liked Bob Colosi (
http://www.guitarsaddles.com/products.asp) his bridge pins/end pins/strap buttons are amazing. I love the Fossilized Walrus products. I've got a set of both bridge pins and end pin for my guitar. They are so gorgeous. I'm thinking of getting a strap button in Fossilized Walrus for my uke but I just can't justify putting a hole in a high end uke no matter how small and "safe" it is to do. It's like surgery 99.999% of the time it goes just fine then you have my .0001% time and the wood cracks and dang it &#^(@*)#
firewood. Not because of the crack from the job but because I put my foot through my uke because so much anger in so small an area can't be contained.
