We get a lot of questions on UKC and loads of brilliant answers so I thought that I'd provide feedback.

I got the Oregon leccy saw and it has been brilliant.
Ive had a couple of massive loads of wood to saw up with some limbs to almost 40cm thickness. This thing zips through it like butter. The setup was pretty easy, chain tensioning straight forward, and when operating, its quieter than I was expecting.
All in all, seemingly a very capable saw which has already paid for itself in time - the amount I've had to deal with would have taken me weeks of manual sawing and at least half a dozen handsaws and this little beauty has taken me about 90 minutes of cutting and saved my tennis elbow ridden arm some massive pain.
Highly recommended.
