Long time lurker of the forum. Just received my new YS640 today. Ordered it with the second upper grate, two probe ports and three grilling grates with the grate tool. Like others have said, this is a TANK! Well built and heavy as heck! Got a few shots but I won't be able to fire it up until Sunday. Can't wait. Until then, enjoy the pictures.
