Weber manufactures many different grills in a myriad of colors with LP or natural gas, but their most popular grills are from three families; Spirit, Genesis and their premium Summit. You should consider any of the models depending if you want to cook a few burgers to smoke meats.
Weber is the lowest repaired appliance sold appliance at Yale, and reliability is the main selling point with Weber. It works and is a better investment than buying a cheap grill every 3 years.
On the premium side, Weber offers features of the pro grills for way less money. The real difference between the three is size, BTU output, rotisserie, searing capability and features like a smoker box and side burners.
