I've been searching for a decent lock miter shaper cutter, and prices run from $50 at Grizzly to $900 (on sale) for an adjustable unit from Amana. Many fall in the $300 price range, and with only about 150 feet of lock miter to run that seems to expensive. I generally buy Whiteside router bits but they don't make cutters. Although I have few Grizzly tools I'm not sure of their quality on items such as cutters and router bits. Opinions on the Grizzly or suggestions for a reliably good source?
