The price seems a bit high for a used one. You can buy a Texas Elit with digital thermostat free shipping no tax for $1000 from a guy in Idaho. My buddy bought two from him. You'll have the extra grill spce when needed. Here is their link. http://www.bbqpitsupply.com/
Here is the deal on treager pricing. All dealers are reqyuired to stay within a tight retail price and are no longer to publish the prices on-line. They can however get better deals buying large quantities and therefore can provide services like free shipping and thermostat upgrades. It's a win win for the buyer. I would call these guys first. I know a guy locally who deal Treagers and he can't compete with the Idaho dealer because the Idaho shop deals high volume. http://www.bbqpitsupply.com/
Regardless, if you go Treager you will be please and will most likely be using it more then any smoker grill you have owned. That is what happened with us and a couple friends who bought them. Hard to turn out bad prodcuts on a Traeger.
