David Klose is a phenomenon of a human being.
His pits are amazing to cook on, I have had the pleasure a few times and they are built like tanks, heavy and solid. It has been my dream pit for a long time now. It isn't a reverse flow, and there in lies some of the reason it has lost a little shine for some, and they are pricey for a large pit. Still, they are great smokers with excellent quality.
I really dig Shirley's and consider Paul to also be fantastic, and one thing I like about Paul, is I have never heard him run down another builders product. I think that is a big deal.
