Well, new to me, anyway. Probably just ignored previous notice because of the prices.
In Harbor Freight's circular promoting their Sidewalk Sale March 8-10, they have:
12" Sliding, Compound, DOUBLE-BEVEL Miter Saw (with laser guide). Regular price: $199.99, web sale price: $169.99, Sidewalk Sale price $119.99!What's different from a regular or sliding miter saw is, when looking straight at it (not down), the blade will rotate 45d clockwise and counter-clockwise. Check the small pictures at:
Competitor's offerings are in the $400-$600 range (DeWalt $399, Bosch $539, Craftsman $599, Northern Tool $399, Jet $739)
