Make the money now because I don't think the market will be as demanding next year. The Toyota Prius was impossible to get when it first came out. Buyers paid a premium and were put on waiting lists. Drivers were in a panic over rising gas prices. If you had one, you could sell it on e-bay for more than you originally paid for it. But after a year, consumers decided they would still rather drive SUVs and mini-vans even if it cost them more. When we bought a Prius a year ago, we had a huge selection to choose from and negotiated the price way down. Gas was near $4 and there was still no run on the hybrids.
If oil stays down over the winter, there will be a glut of "barely used" wood stoves on the market come Spring/Summer as people try to recoup the money they put into them. They will have discovered that wood stoves mean work one way or another. If you want a wood stove to be cheap heat you need to scrounge, cut, split, haul and load wood for at least 6 months out of the year. If you don't want to do the work to get the wood, you have to drop 150-250 for a cord of seasoned wood and you still need to haul and load 3-4 times a day. Those that tried to do it cheap will have only paid $100 for a cord just to find out that oak was split the day before it was delivered and they will come to believe that the much vaunted wood heat doesn't really exist because it is almost impossible to start a fire, it doesn't give off much heat and hisses and pops all the time. Not to mention the mess inside the house.
I'd bet that 2/3's of the brand-new burners from this winter will not try to burn extensively next year and at least half of those will sell their new wood stove to buy oil or propane or whatever. I'm already seeing chainsaws and splitters on craigslist and in the paper listed as "just bought, used once." They had no idea what they were getting into and now they want out.
Like with most activities that requite foresight, planning, sacrifice and hard work, people will decide they would rather pay extra for the ability to sit around and watch TV instead of making a commitment to wood burning. I know a guy who bought a brand-new NC-30, then decided to buy a tank of oil instead of chimney pipe cause the price of oil dropped so much. Another neighbor bought an expensive Jotul but stopped using it because of the smoke and mess. I'm seeing plenty of ads with people asking for free seasoned wood - in mid-november! It looks so easy on paper, I suppose.
On the plus side, I'm figuring on replacing both our older non-epa stoves some time next year with 2 "barely used" ones off Craigslist. And hopefully purchasing a couple "used once" chainsaws and maybe a splitter.
