At a little less than 3 bucks a stick, I would consider these one of the best buys for a smooth, medium bodied smoke. The Oliva Serie G Corona.

After that, for a spicier smoke, I like the Montecristo Peruvian Buena Fortuna. Under $4 and about as cheap as you can find a Monte. (They also have a special going now with a free humidor and lighter that comes with it.)

For the money, the Chateau Fuente, and just about any Sancho Panza you can find are pretty decent too.
