Totally go with Cuba. A buddy of mine spent two weeks there recently with his MF system and has some incredible images because most of the infrastructure is stuck in the 1950's (when the U.S. put on the blockade). This being said, the people and culture is truly one of a kind right now and given that tourism is only going to increase there in the next years--Obama has already made gestures about lowering the ban on U.S. good--it could be just a matter of time before it turns into another Jamaica (watch the documentary Life & Debt).

That's my $.02
