What size gas chainsaw should I get for cutting firewood a few times a year?

Get a 40cc gas chainsaw like a Stihl MS 250 or Husqvarna 440. It’s light enough to handle, powerful enough for logs, and won’t sit unused like a pro model. Avoid battery saws (dead batteries) and cheap no-name saws (hard to start and fix). Spend $300–$400 on a brand with dealer support, use ethanol-free gas with stabilizer, and it’ll last twenty years.
