I agree with you, BBQ. It is quite good. I have always seen the Dickel Barrel Select priced minimally in the lo-mid $30's. So, if you like it, and can get it at $20, you should buy extras.
So far, the only bottle of Barrel Select I found was $40. It might make a good gift for my dad since he's a JD fan but it's not worth that to me. Hopefully it would keep him from drinking Crown Royal for a while
