From a monetary perspective, I'd have to say its the Opus 22 collection that I've been staring at in my humi for a couple of years now.
Not really a single stick, though. That would probably have to be the remaining 4 Don Arturo Gran AnniverXarios I'm keeping for a special day with my herfin buddies. It used to be 5 but I was weak and smoked one a year ago - what a fine stick it was...
