Smoke, keep in mind the new 2017 MAK 1 Star is now the same size as the 2 Star, so you will not be sacrificing ANY space at all, especially if you get a 3/4 or full upper rack.
The new 1 Star also has the new FlashFire ignitor, Ash clean out, pellet dump door, and you can add some of the other features (FlameZone, MAK Griddle, etc.) later as budget allows.
You will simply not be disappointed!
