That's a good looking saw. I've read about the fuel injected one and watched some of Buckin' Billy Ray's videos on it. I like my saws, been running them since I was 7 years old. My first was a Canadian Precision bow saw my Dad bought in 1947. I've run just about every brand made since then but my alltime favorite was my Stihl 044. Ran that bugger for 20 years until I thought I was going to retire and sold it. Stupidest move I ever made. I'm down to 3 now, an Echo 341, a Husky 455 Rancher and an Echo CS620. That's a good saw. I just put a Stihl lightweight 28" bar on it so it balances much better. I'm no longer a logger but cut my woodpile every year. Probably don't need a pro saw, but they run much better and can handle the 3 and 4 foot diameter stuff I cut.
My daughter rags on me about cutting at my age (81) but after growing up and doing it most of my life it's in the blood. Cutting a woodpile is ingrained. Hell, I'll probably die with a saw in my hands. I think I bleed more sawdust than blood. Great therapy out in the woods with a good saw singing to me.
