I was going to build an extender using a Weber grid and bolts, but I just found this for 19.99 on eBay with free shipping. I read some good reviews on it and it's got to be better than the BGE and not much more than building my own. If I'm wrong, I won't be out much.
I love Thomas Handy. It is released once a year in the fall by buffalo trace, so get it early before its sold out! Another great one is George T Stagg, also uncut barrel strength. My bottle is 143 proof! Wonderful flavor. Also limited.
