Maybe clean the current one first and see how it does.
I suggest getting a new gas grill and cleaning it after each use. You'll never have flare ups that way. For me propane is the best all around option. Keep an extra filled tank on hand in case of an emergency and you can cook if the power goes out.
Charcoal is fine but it's slower and harder to control the temp - you can't just add more coals to quickly bring up the temp. Plus they can cooked unevenly depending how good you spread out the coals.
