The 300 Series saws are not great in the ergonomics department, but the engines are very good performers.
Working on the saw can be challenging in the area of the airbox with the carburetor, impulse line, fuel line, throttle wire, and the choke all coming together in a small space.
I think the only parts that are in short supply are the brake bands.
