Yeah I know what you mean, spend your life trying to keep them in good nick. I have a Masterbuilt 560, and it has cast iron grills, they are great for searing as they hold the heat so well.
Have a check what extra stuff comes with it. Different variations come with different accessories. I'd say the hinged grate is pretty useful as are the charcoal baskets.
