For what it's worth, I recently purchased a Black & Decker CS1518 electric chain saw off Amazon. I was looking at various flavors of gas powered Stihl saws from the local dealer, but was really not wanting to deal with another 2-cycle power tool.
It's 120VAC powered, 15 amp, with an 18 inch bar. It comes with an Oregon brand chain and bar.
B&D has been iffy on their power tools for a number of years, but this thing got good reviews wherever I looked it up. I figured at less than $75 I wouldn't be out much if it tanked on me.
I've cut about three dozen 14 inch long rounds out of the two hardwood trees that came down in last year's tornado, plus many smaller branches and such off the same trees. The trees are 24 inches in diameter, so it can handle large stuff well enough.
It's easy on bar oil, and the Oregon chains cut like butter through the hard wood as long as they are sharp.
Overall, it's been a very good saw thus far, and I'm quite happy with it. I've got a lot more wood to cut with it, so that will give me a chance to see how it holds up over time.
