I just got one of the fanciest capos I've ever seen - a Thalia brand capo. So you can judge for yourself just how fancy, I've posted a new review here.
I've been using this for a couple of weeks now as my main capo and it's definitely working out for me. The catch is that it's not a cheap buy - see the Thalia site for pricing and options, but you get a lot for what you pay for, including the ability to customize the capo for just about any instrument.
Anyway, happy reading, and until next time,
