Ive had my inexpensive Kamodo ($300) for six months & have cooked a lot of meals on it.
The cooker is an insulated steel kamodo.
It has an interior fire sleeve that protects the wall of the cooker from direct heat & the sleeve & the interior wall of the cooker are porceloin coated.
It's built onto a cart with wheels & 2 side shelves.
It has a 20 inch cast iron main grate & a 14 in upper grate.
It will cook a lot, 40 lbs of butt, or 5 whole chickens , a whole brisket & a butt, or 8 racks BB ribs.
It's a good smoker , will run 15 hours without refueling..
It " likes " to run about 250 - 290 F , their is a fine line trying to run 225F between keeping the temp there & the fire going out. The insulated cookers require so little fire torun 200-225Fthat the fire may not be self sustaining.
It's a good grill gets plenty hot to sear & cook quickly.
You can smoke then sear on it ( my favorite way of cooking steaks, burgers & chops) but takes a little gymnastics , not as easy as my Horizonal cooker.
I took the insides out to clean & inspect the firebox sleeve & interior & no signs rust, chipping of porceloin etc. only problems I've had we're a couple bolts loosing & replaced with locking nuts & burned up a gasket with a grease fire, took 2 minutes to replace & they sent me one free.
I like this cooker & I'll probably use a lot in cold weather.
I could easily use as my only cooker if space or other considerations kept me from having specialized cookers.
