The best deal I got on a cheap chain saw in the last few years was a McCulloch McCat 16" chain saw on sale at Home Depot for $99 in the case.

There have been no chain saws ON SALE in this area since hurricane Katrina. Probably the best buy for someone who uses it very rarely is the Poulan Wild Thing which is usually about $20 cheaper than the Poulan Pro.
All chain saws now have durability period ratings on stickers on the saws. The McCulloch Durability Period is 50 hours. The Poulan Wild Thing Durability Period is 125 hours. I forgot the rating on the Pro. The durability period rating is a good guide to how long it will last. Forget about how long your friend's grandfather's chain saw lasted. New ones are made different and don't last as long. I would like to know what the durability period rating is on a professional Stihl saw.
Hurricane Katrina blew down 60 large trees in my yard and I spent 6 months, 7 days a week, 10 hour days, cutting down and cutting up these trees. An average of 45 hours per week running time on chainsaws. My McCulloch, which was already a year old, lasted about 3 weeks before every thing wore out on it. I bought a Poulan Pro and it lasted about 4 weeks before the compression was too low for it to start when hot. I brought it back to Lowe's and they replaced it. The replacement lasted about 4 more weeks and wore out. I got a Wild Thing and it lasted about 4 weeks and I brought it back to Home Depot and they replaced it. About 4 weeks later they replaced it again. 4 weeks later the clutch sprocket wore out and they would not exchange it anymore. I bought a new spocket and bar and it lasted about 3 more weeks.
I put on new chains about once a week. All the replacement chains were better than the oem chains. They had larger teeth and more teeth which means they took longer to sharpen but they cut faster. Low-kickback chains cut slooooow.
I borrowed a friends 24" antique Homelite for a few weeks to cut some very large trees. It was still working great when I returned it.

My arms were worn out from using this monster for 3 weeks.
Then I bought another Wild Thing which I accidently dumped out of my fel into a fire after a couple weeks use.

Then bought another Wild Thing which I used for a couple weeks till I finished the job and now use only occasionaly.
A cheap one will last an occasional user a much longer time if you mix the gas correctly and use Stabil, keep the bar oil full and grease the bar-end sprocket, keep the blade sharp, and stay out the dirt.
