Consider these two factors when shopping for a grill -
Q. Do I grill with the grill lid down and let the meat cook while I am with my friends?
A. Grills with Sear Burners are not designed to be left alone nor should to close the lid for extended periods or at all, especially if all the grill burners are ALL SEAR Burners.
Closing the lid will creamate your grill and your food. With Sear, you need to stay with your grill and babysit your food.
Q. Do I want to have the abillty to change out the sear for the standard burner?
A. Most are not sure but the answer is a resounding Yes, so look for grills that allow you to "Plug N' Play" your burners. It gives you better Flexibiity.
