Lowes carries a ceramic cooker now (cannot remembe the name) and the top vent looks like a pipe with a swing cover attached. Cheked it over (over $650) and I do not think it better than a Keg, but I am biased!
That would be the Bayou Classic Cypress, pictured in my avatar. So far, I've had a few minor problems but their customer service has been top notch.
Lower vent wasn't sealing properly, but we've seen some Kegs with that issue as well. Fixed with hi temp silicone.
The lower firebox developed some bad cracks. Customer service sent out a new one as a replacement. The replacement is a new design with a factory slit in the firebox that should resist cracking. I've got it set aside until the day comes when I can't use the original any longer. They easily could have told me that cracks were normal but they sent a replacement.
So, does it cook any better or worse than the Keg? I'd say about the same but it does seem to hold a low temp easier than the Keg. Honestly, I really don't have a preference as to which one I cook on - whichever needs less cleaning I guess. I do like the double grate convenience the Keg offers. And I did wind up buying a Craycort CI grate for the Cypress since I like the CI grate in the Keg.
Is it worth more than twice what I paid for the Keg? $700 vs $299. Probably not, but then again, I purchased it before the Keg and the Kegs were being sold at the HD discount price. Had I known about the Keg at the time I purchased the Cypress, my decision would have been different. But I'm lucky to own two excellent grills for my new hobby.
