I’m a fan of The New York Times’ Wirecutter reviews. In this one they offer their take on the best camping stove. If you don’t want to click over there, the Coleman Classic Propane Stove came in as their pick. At about $44 it seems like quite a deal.
Another stove, not included in the Wirecutter review that you might be interested in none the less, is the ultra-slim GSI Pinnacle Pro Stove. It boasts two 11,000 btu burners (compared to the Coleman’s 10,000 btu burners) and packed height of only 1.4″. This stove just came out and I think they’re still hard to find. Expect pricing in the $175 range.
