I need advice on which chainsaw to buy. My husband passed away and I need a good, reliable chainsaw that isn't too heavy or too hard to handle. He used a Stihl 029 and an 056 for many years. Milled a lot of lumber with the 056. We cook and heat with wood, but I now have a propane stove. We still go through about 8 cords or so. I'm in my late 50's (and not as strong as I used to be) and my son is 17 (strong as an ox). Trees around here are usually about 10" to 14", but some are larger. I have a bandsaw mill now for lumber. Do I need to get a saw in the Professional level, or would a Homeowner Stihl be good for us? Money is an issue, but safety and reliability are most important. Thank you.
