I picked up two older 3 burner webers in the last couple months, and the best part is everything can be easily found and replace. I have replaced the burners in both, bought the drip tray for one and am waiting on a new set of bottom slides that hold the bottom shelf for the drip tray on one. One is a platinum and the other a genesis. Most of the time I only use 2 burners so I can have a cool place to move food to, or so I am not cooking directly over a fire, so a two burner should not be a problem. Just shop around for best prices on things they can vary a lot. Nice catch.
