I've had mixed results with grizzly. I have a buddy who has a grizzly planer with a helix style head and he loves it. I saw a combo planer/jointer that had lots of issues, but with a couple of days of tuning, calibrating, and cursing it rose to mediocrity. I had a scroll saw that was the worst tool I ever saw outside of Harbor Freight.
You might get better feedback if you mentioned a specific tool model and asked for
input from owners.
