For a family get together with pops, I'd also think about a mini WSM. Smokey joe ($30), 32 quart tamale pot ($20), Tuna can ($2.00), cooking grate and charcoal grate ($20). Stainless hardware? B ess.. Grab the cheapest hw you can find and give them a vinegar soak. All zinc coating will be gone in a flash (or slightly slower).
Very easy to learn how to use while being efficient on the fuel usage. You can even cook a whole packer brisket on a mini, fold it over.
