Thx for the response. I’ve actually talked to the owner of the company in New Zealand (Jake Peterson)and the U.S. rep at Smith Sawmill Service(Jay Willoughby).Both were extremely helpful and a wealth of information. Very refreshing dealing with people not concerned just with sales-but service and to make folks happy with their productSome of the earlier models had issues with the guide track flexing too much. I believe the manufacturer made some improvements but you better do your research. I have no first hand experience fwiw...just internet reading on some forums.
