Brinkman has a combo that looks like it would be good. Contact some of the members with that unit and see thier comments. Versitile without a doubt , and the price saves getting two different units. Not a high standard ,Thick metal unit, but Mods, will fix that and increase you prouctivity.
Not a bad choice for an unseasoned Smoker as you are.
Good luck , good cooking and as always . . .
