A timely topic for me. I have an Echo brand gas saw which I loathe. Hard to start, runs poorly, since the day I brought it home. So I use it, but I hate it every day.
I recently had to buy a string trimmer and decided to go electric, if only so my wife wouldn't need to learn to deal with gas mixtures and pull starts which are difficult for her slight frame. And of course if you're going to start buying anything with $100+ batteries, so your homework and plan ahead. So as part of the string trimmer research I researched chainsaws, even though I wasn't sure about going that route, because if you're going to have those batteries, and are thinking about electric chainsaws, then you want to be able to share batteries. Some manufacturers make great string trimmers and so-so chain saws. Definitely makes the purchase harder.
In the end I went with Milwaukee. My first couple of hours with the Milwaukee string trimmer and 8AH high output battery have been great. It's not a light trimmer, but it's solidly built and I get about an hour of trimming on the low setting, which is all I've needed. This model has the Quik-Lock setup, so you can attach the motor +stem to other attachments like hedge trimmers and pole saws. Seems like a great idea to me. (They have another string trimmer model they sell with a 9AH battery but no Quik-Lok, so pay attention if you're shopping).
I was pleased enough with the string trimmer, and had another thoroughly aggravating day with the Echo, that I ordered the Milwaukee chainsaw with 12AH battery and free blower (a promotion - got it at Home depot).
Unboxed it yesterday, it's very sturdily built, but haven't tried it yet. Didn't see anything that smelled of "toy chainsaw". It's heavy, sturdy, and ready for business, will try it this weekend as I have downed trees on my grass ready for work. And now I have two interchangeable batteries, two of the largest Milwaukee sells. The batteries alone retail for about $300+, so if you're going electric you're really committing to some expensive battery technology, make sure you can get the most from it. Try not to drop it
I also used to use a corded electric chainsaw a lifetime ago in suburbia. It was actually a great experience, I could always rely on the thing to get the job done, and never had to worry about gas going bad or oil mixes, which is probably why I was open to the idea of a battery powered device now (when an electric cord wouldn't reach past my driveway).
