Barbie, you asked earlier about smoke flavor on a gas grill...get a smoker box and buy some wood chips. You add it to the gas grill and the wood burns (you've soaked it in water, first) and smokes and adds the flavor you want.
Also, the Volcano 2 can use charcoal, propane, OR wood. It's a nifty gadget, albeit a little pricey. I love mine (haven't tried the gas part yet.)
There's a thread here somewhere about it (I think under Gadgets and Gizmos.)
ON EDIT: Here's the previous thread on the Volcano 2:
