I mostly just use the ground, but when at home, in a townhome, I don't have the availability of a lawnmower. So all cigar ash and buts get kept in the latest emptied coffee can.

Although, if I had all the money in the world, I did once use a sweet single-cigar crystal ashtray that I have yet to find one like it. I used it at a fancy-schmancy hotel a few months ago. They actually took away the cigarette ashtray and put the cigar ashtray in it's place.
