I had a law enforcement friend who nabbed a fellow coming from Cuba via Honduras with the biggest cigars I'd ever seen - a foot long and an inch or more in ring. The fellow had tube pockets sewn into his coat, and it was a lucky stroke my friend found them. They were the most incredible smoke ever.
If you don't mind spending some dough, the Cigar Connection in Miami (305-531-7373) has some excellent chocolate cigars. They are $75 for 50 (or 25?), but are worth every penny. Not only is the smoke great, but the taste is better. They mail all over. I think they make the cigars right there, and other cigars I've had from them were good too. Also, Key West has a lot of good little cigar makers, but out of the way.
Remember, not all Cuban cigars are good, and some are horrible.
