So I am looking to buy a grill for my apartment's patio and stay within a budget of under $100. My apartment is in Philly and is fenced in, although we share a back yard with the house next door (no fence between the two yards). I am not opposed to gas, but I think charcoal will be cheaper and less appealing to those who may look to steal it. What do you guys recommend? I was looking at the Weber Silver serious, both 18.5" and 22.5" diameters.
