Kent, I've got some Mesquite I'll give ya. I personally don't care for it. I work in Wentzville.
We're lucky to live in an area (on the IL side anyway) where there's plenty of orchards. Give some of them a call, they might hook you up. I usually get my wood from people who've just cut or trimmed their fruit trees. I just offer to haul some or all of it off. Of course you have to cut and age it yourself. But it's a quick way to get a good supply of wood. Cheap.
Also, I always buy oak or hickory to burn in my fireplace. There's always a few good sticks left after winter. I use them too.
One other option is to go to Schnucks and get the BBQers Delight pellets. They have a nice variety usually. (at least the Alton store does)
