I got one of these too JonO, not sure how we ever lived without a kamado.
On the deflector etc, there’s a brilliant pan with eye hooks solution on this site; I also had everything custom made by a local metal fabricator, there’s a YouTube video with a real guru showing you what to do for metal plates and steel supports. I also pimped it to move around the patio...ie made a base with wheels.
So far I’ve tried almost everything, to a high degree of success...pulled pork, steaks, ribs, smoked fish, chilli, whole chicken, corn. Just go for it - kamado is your new best friend!
