The first of the best rated gas grills under $300 is the Brinkman Pro Series 2210. A very basic grill, it offers a 636 total square inch area for cooking, which is very large in comparison to most in this price range. Its 12000 btu burning capacity is not that powerful, but it does offer three burners.
While the cart on this gas bbq is not as sturdy as it could be the burners are made of cast iron and should last a very long time. This grill was designed to be very large and quite inexpensive. It succeeds on both counts.
The next on our group of top rated gas grills under $300 is another Brinkman Pro Series, model 4400. This grill is found at Wal-Mart. Designed to look like a knockoff of a Weber grill, it has some stainless steel construction and good cast iron burners. The heat output on this grill is good.
This member of the best gas barbecues under $300 family has four burners, giving off 15,000 btus of power each, 630 square inches of grill area, a 12,000 btu side burner made of brass, and a cast coated in porcelain.
Brinkman again earns another grill listing as one of the best rated gas grills under $300 with its Charmglow grill. Sold only at Home Depot, this grill is made completely of stainless steel. It is heavy and durable, the primary reason it is one of the top gas bbqs under $300, with 45,000 btus and 456 square inches of cooking area.
