Indeed, it is a very sweet machine. It's very smooth but does serious work. It's especially nice to have a 10-1/4" jointer in such a small footprint. Rust on the blades is usually easy to remove with water or oil stones, and rather irrelevant as long as it hasn't created pits in the cutting edge or bevel. And you really only need one set of knives. I can take them out, sharpen them, and have them back in in less than 45 minutes. Fast enough for a hobby shop.
