The Bahco/Kershaw works well and is a good balance of size and weight. IMHO, the Silky Pocket Boy models are too heavy for the size of the cut given. If you want a light more compact saw, the Gerber Sportsman's saw is only 3.5oz and about $12.
I'd like to get my hands on the Silky Super Accel to see how they compare to the Bahco.
I think the chainsaws are heavy, require two hands, and they aren't handy for notching and other wood work.
