what i didn't like about the horizon was it is $100 more for a 20"x36" vs 19"x40" for the old country.
the exhaust of the horizon is up top as opposed to at grate level for the old country. the horizon does not have a baffle at the firebox and the old country does. the old country comes with a heavy duty steel plate with holes in it to seperate the fire from the bottom of the firebox. the old country food table shelf is retractable.
you might have to do some mmods to the horizon.
