ill buy every bottle you can find for $200....
I have several bottles of 10y and 12y that go for well over $300-$600+/e.
OKI, Blaum and some of the best Willett is an MGP bottling and are widely regarded as some of the best bourbon in the world.
This stuff is not something you will find on shelves, specially in Ohio. It takes being in with store owners and usually spending decent money at a select few stores. There's plenty of bourbon that I really enjoy and that I share with friends that are getting into it. Eagle Rare is one of the best in my opinion thats pretty easy to get and is priced really good (around $30-$35 retail).
I will admit, I have had a large collection of bourbon over the years, but have cut back and really only bought the things I will drink, so my tastes are not going to be the same as the next guy.
I was able to pick and buy a whole barrel back in Feb with a local store to me that I really like and it turned out to be a great bottle and it was relatively affordable until the secondary market got ahold of it. Last I saw it was was going for $450/e.
Here is a few pictures of the bottles I was talking about. If you see any of these with the purple or green tops and they are 5-9years olf of Willett, id buy them to try if I were you. The Blaums will be almost impossible to find in the wild, but if you get them, buy them. Fantastic bourbon.
