inguy, If you are going to buy an OWB, you really ought to buy a gasser from one of the more reputable manufacturers. If a dealer told you that there isn't much difference in efficiency between a conventional OWB and a gasifying OWB he is telling you a bold faced lie. In most cases you will go through half the wood with a gasser. There isn't any extra work in wood preparation, as if you want a conventional OWB to function properly wood needs to be split and especially seasoned properly. There is a little extra maintenance involved, but from my experience operating two different OWB gassers, that maintenance only takes about 10-15 minutes/week. I'll wager that the biggest reason the dealers are trying to push a conventional OWB on you is because they have too many in stock and the new EPA regulations for your state will be out soon, so they want to move their inventory. A gasifying OWB is the only way to go if want to keep the mess, smoke and fire hazard outside. A Garn or Wood Gun would be your best choice for a gasifying IWB.
