Padron 1926 or 1964 maduro
Kristoff Maduro ($7-$8, this is currently one of my favorites, very rich flavor, tough to find though)
Diamond Crown Maduro (I recently had a No. 4 maduro and it had a creamy rich classic maduro flavor with impeccable construction and tons of thick smoke, $12)
San Cristobal
Rocky Patel Vintage or Decade
I prefer the Carlos Torano Casa Torano Maduro over the Virtuoso (get both!)
AF Work of Art maduro if you can find one
Don Pepin Series JJ maduro (very unique smoke)
Alot of people on this forum love the Ashton VSG (for the price it didn't much for me, but I think every smoker should at least give it a shot)
Camacho cigars are a little pricey as well and seem to be popular on this forum

I don't buy many expensive smokes so there's alot I haven't tried...
