I don't like to use anything fancy for outside. In fact one of the ones I use is a CI smiley ashtray, ceramic, that cost me $5. Is has sat outside for three years now. Like Brad mentioned the Stinky ashtrays as great and can be had on CBid for about $15, but I have a concern using them in the winter outside as the freezing metal can damage a wrapper, especially near the cap when it is wet from smoking.
