My vote would be for a Weber Kettle. Very affordable and one of the best cooking machines ever created. If you are getting a gas grill, I suggest spending the money and getting something decent, like a Weber.
Some background. I cook outside A LOT. I have charcoal grills, gas grills, smokers and a pig roaster. I've done competitions and started a bbq company. I've backed off on all of that stuff but still am passionate about cooking outside. I used to own a Weber gas grill and found it to be amazing as gas grills go. No hot spots, no flare ups as long as I kept it reasonably clean, great warranty, durable and just fantastic all around. I gave it away to a family that needed it because my father in law gave me his grill. I used it until it finally wore out.
I then bought a Weber Kettle but I got a larger one because I typically cook for large groups or I cook multiple things at the same time so I dont have to cook as much during the week. I bought a cheap gas grill because I figured maybe I there would be times I didnt want to go through the hassle of using the charcoal. The cheap gas grill sucks to cook on. Flares up like it's crazy and doesnt cook even. Therefore I have used it 3 times in the last year. And it turns out that with a chimney and good fire starters it is just as easy to use the charcoal.
Another tip. After cooking, close down all of the vents completely. This will make the fire go out and conserve a lot of the coals in the grill. Next time, just use the cleanout on the bottom to get rid of the ash and small pieces and you are left with a pile of useable coals. Now you just need to light maybe a half a chimney of new coals and put them on top. Let those get the old coals going while you prepare the meat. I also usually only have coals on one side of the grill so I have a hot side and a less hot side. Or maybe 60/40 or 70/30 but I always leave a bail out spot.
In summary, if you want the gas grill, buy a good one. Cheap grills just aren't worth the hassle. Or, as mentioned, you can get a Weber Kettle charcoal grill for cheap. They are absolutely amazing and with a chimney and good fire starters, they are just as easy and fast as gas.
