It's true. The Origo boat stoves are big bucks. I think that my two burner Origo 3000 went for a couple of hundred bucks but that single burner Origo 1500 that I picked up in a junk shop not far from where I live was so cheap that I couldn't pass it up. Would you believe $5.00? I reached for my wallet and pulled out my money and grabbed that stove like a Hobo on a hot dog!
All it needed was a round rubber gasket and the flame diffuser. I sent away for the gasket which came to about $4.00 and the flame diffuser was free. These stoves didn't come with them years ago and the Origo company would send one out free of charge.
I don't like pressurized alcohol stoves. The canister type stoves are safer to use. As I mentioned though, alcohol is very pricey and you need to make sure that the canister is cooled down before you cover the canister with the rubber gasket.
I found a neat way of conserving the fuel in the canister by cooling it off immediately with a damp wet rag. I keep the stove open with a stick and as soon as the top of the canister is cool to the touch, I just place the gasket on it and use a metal plate to weight it down.
When the stove lid finally gets cool, I remove the steel weight from the canister along the stick, and then I close the stove.
I've been using my single burner Origo which allows me to move my table over the sink. I hadn't been able to do that with the two burner stove since I change my galley cabinet over. I usually slide the stove over to the left when I want to use my stove-top oven or my stove-top grill. The stove sits on a stainless steel restaurant type steam steam table pan which is screwed to the top of the cabinet, with a non skid rubber mat under the stove to keep it from sliding. With fuel prices as high as they have been, I find that I can get away with a single burner stove for all my meals on board.
