Man, Matthew what an operation to get that all the way from the States! I could have sent you that capo and the sticker, hihi!
Anyway, there was a thread already on the forum about capos. As I work in a shop I have the opportunity to try them all. Briefly, my evaluation on the most common ones:
Dunlop spring capo: reliable, but people often say they're in the way as the 'clamp handles' (can't find a better word) are on the back of the neck.
Kyser spring capo: easy to use, not in the way (clamps from the top) but doesn't look so pretty
Schubb: easy to use, but not as easy as the above, but still allows quick changes, nice looking and not in the way
But Matthew found one of the cheapest, haha! The Bill Harris works fine, but is not particularly handy for quick changes. And over time the elastic will stretch... and really, I only find these capos on old banjo cases these days
Mind you, the BH is a 10th of the price, so you can't have it all. I don't use a capo, but I would go for the Schubb myself.
