I have the model on the right and have run a couple thousand feet of sawmill lumber thru it - white oak, red oak, beech, poplar, cherry - most of the boards were 8" to 10" wide. As stated it generates alot of chips and a large shop vac won't keep up with it, I just let them fly and clean them away when they get too deep to work in. With the white oak & beech you do have to help the feed get the boards thru some, especially if it has much moisture in it still like I've done. The beech I planed was quite wet still but the planer did a great job for what it is. I'm on my second set of blades and I think I'm going to try and touch-up the edges on the used ones as they don't have any chips in them, just lots of use. I bought this planer just slightly used from a friend for $200 and I consider it a bargain. The replacement blades (3) cost me right at $54 shipped. I had no problem changing the blades and there is no aligning or anything to do, very simple task.
