Running the gas line shouldn’t be that much. If you’re mechanically inclined you could do it yourself.
Just make sure you have enough clearance over the grill where you’re installing it. I’m not just talking about fires but grease and smoke stains as well.
Make sure you’ve got clearance in the back and sides as well. Helped a friend build a large screened deck and he decided to grill when we got finished. You know, vinyl siding takes strange shapes when it gets too hot.
You can get a Ducane at Costco. Good grill not too pricey. You could also get a combo grill/smoker.
