No, got a Mark II.
Althought did not see the Buck 24, I saw their wood versions and from several design perspectives kind of too lenghty to get into here, it was kind of a down grade to the Mark. I would still like to see the 24 and especially the grate design. Don't think the Buck has a internal cavity for heating air like the Mark but would like to be proven wrong.
After experiencing 35-40#'s of red/white coal burning in the Mark at 2400 F with 10" high blues, I kinda want the best bulletproof design possible, after all, that much coal is only something like 450,000 BTU's in your basement. Yahhhhhahh
