This was a replacement for a ten year old Q140 (the smaller grill). I grill 3-5 times a week, and it was difficult to cook multiple courses if one required any type of tray, since the tray had to be exactly in the middle in order to close the lid. The larger area of the 2400 solves that problem. The 2400 (and the 1400) cook as well or better as any gas grill I have ever owned. And, it can be used for those like me who live in an apartment, where gas grills are prohibited. Highly recommended.
