Sorry for the late reply, I was out camping for the weekend.
I'm talking about 5-10, but these are big trees.The smallest is 12" or more, the largest is 24" or so. But, once the lot is cleared, the saw will get little use.
Summing up what I've gleemed out of these 3 pages so far,
Echo, Huskavarna and Stihl are all at the top of the list for a homeowner.
I'd like to get this chainsaw for $300 or less but I'll spend more if it is worth it, but $600 professional saws are not something I am interested in.
I totally understand the negative of going with a battery, but batteries of late store much better than older ones. Obviously you read all the comments, so hopefully if you do go with gas you will properly take care of it for long term storage. That said, I'd would still lean towards battery. Ego brand if you aren't into a power tool brand, and Milwaukee if you are going to start getting tools.
We have 60 acres, and plenty of trees. Whether falling on their own, or decided by me, there is a lot more to take care than I realized. My brother was always the one need to get his fix on a gas motor, and I never really touched the chainsaw. Then after that motor got fubared (around the time ethanol took over our engines ironically), I would use a Milwaukee sawzall with pruning blade, and worked for quite a bit more than you would expect. Then I got the Milwaukee 18v 16" and has performed excellent. Granted, I wouldn't pay the $450 it retails for (I do live in Amish country). I got mine with battery for ~$240 (holiday promo & was display), but I would have paid closer to $380 after using it.
The Ego is a 16" brushless, but has a non-traditional tightening mechanism that seems to be less favored in general, but still
1,200 people giving it almost 5 stars, and costs $300 for 5ah, with a 5 year warranty. If you get the 2-year extended warranty from HD, that will cover everything from years 6 & 7 for $45. So for $345 you get 7 year guarantee, that ain't too bad. Plus they usually don't fix it, just send you a gift card for the purchase amount. It's also easy to chat online and get another 10% taken off just about anything, they are usually really friendly. Say it isn't in stock locally, and wonder if you save a little for the wait to get.
I have not used the Ego, but I did see the breakdown video of the Dewalt 60v & Milwaukee M18, and the Milwaukee is by far the better saw. The motor is like twice as large, and has the traditional two nut tensioning system.
