After using a Genesis Silver B for about 15 years (zero problems), I upgraded to the Summit about 5 years ago.  I was very excited to get it after only having Weber products in the past.  From the beginning, the ignition/burner control knobs would split and lighting the IR burner is nearly impossible. Now I'm having difficulty lighting (2) burners, they only ignite from neighboring burners being lit.  For the amount of money this grill cost, I would shop around and look at other options next time.  I really wanted it to be better, truly.
