This is one of those things that you would like to have 'just in case.' (and not just-in-case for the zombie apocalypse, but just in case a tree falls down at your house, your parents, etc.)
I hesitated before, but will pick this up on the woot-off. Reviews have it more expensive. There's a website called ChainsawsDirect (seriously? a website solely for chainsaws? what will the interwebs think of next?) and they sell it for $209.
Overstock has it for about $150.
Both websites gave it fair reviews.
