I'd rather spend the money on larger and heavier and bigger motor than a spiral/helical head, but I also I have the space and power for it, which I know everyone doesn't.
Nor I. As a hobbyist I bought a very well used (read rust) Delta 15" planer (came out of a cabinet shop) and rebuilt it over the winter some years back. Was very careful with set up, had existing knives sharpened, worked great and still does. Have changed knives once due to nicks. Have straight knives and happy with it, although changing knives is a pain. Have had it about 6 years now. Randy
