I have the 2200 too, bought about half price when the snow was on the ground last year. Mine has the heave cast grill also, it's bloody heavy but gives an even spread of heat.love my Q2200, I honestly don’t bother with the charcoal bbq anymore.. cook
With the lid shut and it bbq cooks brilliantly.
mine has the solid cast grill (it’s a few years old now) the new ones have lighter pressed grills I believe - don’t know if this will make a change to the experience, but as I say, I solely use this now.. in fact I love the Q series so much I’m very tempted by the bigger 3200 now.
I'm really happy with it and wouldn't even contemplate the monumental faff of charcoal.
