If you're interested in trying some vintage wooden ones, with or without wear plates, watch this video by chairmaker Peter Galbert: http://www.youtube.com/watch?v=KJHSPSxfrTc. He's actually talking about wooden travishers, but halfway through he uses a wooden spokeshave to demonstrate the technique for controlling the depth of cut. My favorite spokeshave is my LN Boggs shave, but watching this video totally transformed my old wooden ones. You can go light or hog off giant chunks with them, no adjustment required. It's all in the handling.
