So I picked up a barely used Powermatic PM15 off CL for a pretty good deal, now I'm wondering if I should sell it for a standard planer or keep it. I'm not a fan at all of straight knives so it seems kind of pointless for me to have this model. I could switch out the head that's in it but I haven't even ran this planer yet as my shop has yet to be set up. All of the planers I have used had bottom rollers as well as top feed rollers while this one is a solid bed with all rollers being on top, which I like the thought of it as it is very hard to keep the bottom rollers adjusted right so they don't leave a dig on either ends. But my instincts tell me I'll have to be pushing the wood through because the rubber rollers won't have the necessary grip. Have any of you used the PM15? Doesn't even look like they sell it anymore which is a bad sign:-(
