On SP Ashton estates, well, sort of. I've purchased three estate Ashtons from them (Taylor) and have had issues with each one
My first, was drilled quite poorly, but 20 minutes with a tapered drill bit and file made it into a great smoker. But out of the box, not so much.
My second had a pit that popped off, on the bowl, to reveal a tiny hole! (of course it was accepted for return without any further question)
My 3rd was a bulldog, the edge of the diamond shank (briar) was as thin as I've ever seen and I was afraid it wouldn't hold up to regular use. It was also accepted for return without question.
Buying from a reputable seller such as SP does give you protection not found in every estate outlet.
And, do your homework buying Taylor estate Ashtons!
