I'm completely new to all of this. I've been reading and for the about $200 price range I think I'm looking at the Masterbuilt. Any others I should be considering? If I go with the Masterbuilt I'm stuck on the 2 door 30 inch or the single door 40 inch. Seems like the more space would be nice to not have to slice up ribs, but how is that tradeoff compared to the two doors?
