I'm no chainsaw expert, but this thing is a gangster of a saw. I wanted a 50cc saw that could handle most tasks around my 160ac of woods, so I opted for a worked-over 261 as that seemed to be a very popular mid weight saw. I stumbled upon 309 Machine, read their reviews, and watched some of their YouTube vids and was super impressed with their CNC setup. Their turnaround time was MUCH quicker than other competitors. Their email responses to my questions was usually within an hour or so.
The saw itself is impressive so far. It sounds amazing (I opted for the obnoxiously loud Egan pipe; I may change this back to the WCS port) and with the stock .325 it zipped through a fallen 18" Sugar Maple like a lightsaber. It still needs broken in fully so I haven't been beating on it too hard, but I buried the WCS dogs and put some pressure on it and it didn't hesitate at all. Can't wait to see what it's capable of in the future.
I'll definitely be buying either a worked 462 or 500i from 309 in the future.
