^Do this to start, or maybe a 26.75 OGT if your budget will allow it! You will learn they are very versatile, obviously direct grilling but also some great slow smoking, CI cooking and even pizzas all at a good entry price point. Once addicted, you can consider anything from a UDS/WSM to a stickburner (my personal favorite).
