Considering this is a Mexico Regional, I doubt you will ever see any in the 24:24 here. If they were to show up, they would likely be much more than the $300 quoted.
I find it to be a very good cigar. My wife likes them as well. We've gone through 2 boxes already as they have been smoking beautifully. If they age like the other Edmundo Dante Regionals from Mexico they have a good 5-8 years where they become more complex and mellow out a little. The last time I smoked an ED 109 was about a month ago and to me they are past the point where I like them. I paid $315 a box when they first came out and if I had the funds would definitely be buying a few more boxes.
