The pictures and photographs I’ve seen with the Yoder YS640 is Rust. I’ve seen a few of them with only a couple years of use on them with a lot of rust. I don’t own one, but I’m just saying that’s what I’ve seen.
Definitely go with a Recteq RT 700. I have owned three traeger’s. We’re so dissatisfied with them. But a Recteq and it’s been wonderful. Built like a tank. And it keeps temperatures within 1 to 2°. Love it.
I think I answered my own question. I started cooking range, free chicken breasts. I cook them the same way as I did the rubber chicken breasts. I cooked them three times already and they come out wonderful. Goes to show you don’t buy cheap chicken.
