Check the reviews of the newer indoor grills. Even if you can't use them inside, taking them outside may be more convenient than the front yard gas grill.
And to be very, very honest...One of my lessons from cooking school was how to get acceptable results with the least effort/time/equipment/ingredients possible. Unfortunately, the answer was "if you can't bring your game up, you should bring the bar down"... You need to cook to YOUR standards, no one elses'. You might have to settle for a grill that does good burgers, but so-so steaks and chickens. Then just buy ("specialize") in what your set up does well. If the grill is even mediocre, to my tastes, it may be enough to do good steaks and chicken when used in conjunction with a sous-vide.
