Hi, I am in the market for new smoker and looking at the Yoder YS640 but found a dealer down the street that sells Louisiana Grills (no Yoder dealer near Annapolis MD) They are not the same price point but interested if it will work for me. I have searched here on the forum and online only to find limited reviews. Any feedback on the CS-570, CS-680 would be helpful. Temps even, swings, grilling/searing mode, digital control etc. Also the Chimney less Design Thanks, J.T.
