Also......the bigger the engine, the heavier the powerhead. A heavy saw can be tough on us "older" guys backs. I personally like a 20" bar, long enough to take on most trees and provides reach without bending over as far when cutting on the ground or limbing. Depending on the weight of the powerhead, the correct length of bar can "balance" a saw and make it easier on the back.
The pro saws are great, but expensive. A specific recommendation would be a Husky Rancher 455 or the Stihl MS291. Both are 55cc landowner saws and are a good combo of size, weight, and power. Both will handle 20" bars. Both come in at under $500, hopefully even with tax in Kentucky.......

Not being married to any particular political party sure makes it a lot easier to look at the world more objectively... Having said that, MAGA.
