For the money, I'd pick up a MSR Whisperlite then. Cheaper used than a used Nova, Omnifuel. I believe the WL has a longer and better track record too. I have always left the pump in the bottle after releasing the pressure each morning when packing up. No issues. The 8R's and 111's are neat, but the 8'R's do have a small tank, good for at least one meal. I have a few alcohol stoves, they are slow, but work, no moving parts too! If just heating water, that might be the most reliable way to go, but the MSR WL will take about any pot.
