Best gadget buy in a long long long time

I have a Saws All(reciprocating saw) for home use, it works fine but can't compete with a chainsaw for cutting logs. I take an electric chain saw with me when camping. More than once I had to clear a road where a large tree had fallen across it especially early in the season. It works fast at the campsite to cut firewood. I am always looking for ways to exercise my genset without just running it under load for an hr each month and find using this chain saw helps to eliminate this exercise.
