I am looking for opinions on a couple of planers. I have priced a Grizzly 15 inch with Helical head and also a Grizzly 16 inch with fixed table and Helical head. The price difference is insignificant. I have a small 1 man commercial shop and try to buy most of my lumber already milled. This planer will be used for rough sawn material mostly hardwood but some pine. At present I have a 20 year old Powermatic with a Grizzly helical head but it constantly has feed problems that hamper production. My question is will the new planers be an upgrade and if so what is your opinion of each one. Thanks. Bob
