My favorite is my Oliva ashtray. It looks little in this pic but it's really big. They go super cheap on cbid and sometimes come with cigars...

I have this one, too...

I like it but I don't really use it. Everyone else does though.
I don't want to sound contrary, but I've never desired a stinky even though everyone loves them. I bet it'd be nice to have a couple at a herf, though.
I think it's cause I'm a clean ashtray freak. I like to keep them clean because I enjoy making a mess out of them. All my ashtrays sit outside and I'm afraid a stinky would rust up pretty bad, too.
Any of you guys keep your stinky outside and do they rust?
I could sure use one for all the cigarette hogheads that come around here (not that they'll put their butts in it anyways, but the "wow factor" might entice them.)
