I've had them for about a month and love them. Burned them in 100+ hours, but i've been seriously tempted by the CK10s. just trying to figure out what to do with them. Trying to get some reciprocal cash if I do buy the CK10s. They're in perfect condition, and while I don't have the original cardboard box and stuff with me, I do have the tin, the medium and small tips and the cleaning rod. perhaps something like $70 shipped priority flatrate or cushioned envelope depending on how stocked my campus bookstore is. Local pickup is cool too if you're in the Buffalo, NY area. (though why you'd be here is beyond me..) again, this is a feeler, and I'm undecided as to what to do at the moment.
