Something in the 40cc range is great. You can trim for days on end with one and a lot of them have more grunt than you think.
I love my little Ryobi's. They're very light and run great when muffler modded and tuned correctly. They're crap out of the box though. I think that's why there isn't many to be found anymore. People pry just threw them away. I know I almost did. I just picked up another one recently, so they're out there. I didn't dig too much into the Earthquake thread, so I can't comment on those.
I believe that saw is powered by a Zenoa motor... When "liberated", they will run like a scalded dog...
The motor will still be running when the rest of the saw falls away...
