Yes, I have some advice.
Don't.
If you're going to buy a grill for convenience, then why bother buying an expensive gas one?
If you're going to buy a good one, then that rules out gas from the outset. High end restaurants use charcoal. Even the ones that use gas have commercial systems with high heat output. There's also the cleaning of the gas ones to consider. They don't get hot enough to destroy the grease, so they become grease pits. Some have removable parts to help; the dirty bits of my Weber Q120 will go in the dishwasher, but it's no use for a full-on cook-out. Charcoal grills make a bit of ash. Brush it out and you're good to go.
I had a big shiny silver 5-burner, rotisserie equipped gas turd a couple of years ago. I ended up giving it away. It was pants.
There you have it, a completely unbiassed view
