Well, I picked up the Ironwood 650. I have both on the patio right now, seasoning the 650. I can tell already that I'm going to like it better. Definitely like the smaller foot print and the multiple options for the rack. If I need to cook more that it can hold, I also have a BGE, a Weber gasser, & a kettle. I wanted a pellet grill for convenience. Sometimes, I just want to cook outside and not have to build a fire.
Definitely worth the extra $54.
Good for you, now I wish you the best, but you'll do just fine IMO
