You must be glad your not in the 60s and 70s, I ran a mid 70s McCulloch chainsaw back then for 15 minutes, it was practically brand new but my hands was tingling for 5 minutes afterwords, the guy wanted to sell it to me but I already had my first new Husqvarna, L65, so I said nah.
I think anti-vibe has come along way since then on all saws, maybe Husqvarna is the leader on that, either way it is very important and another reason why I like mechanical wood harvesting, I'm a big fan of make the machine do the work.
My Poulan is like that: with no vibration dampener I wouldn't want to run it very long. I only paid 100 bucks for it new though, and it's good enough for what I want it for; something to throw into the back of the truck in case there's a tree across the road. It get rained and snowed on, and if somebody steals it I'm not out the price of my good saw.
