I bought one, and finally have had the chance to use it. It worked like a charm. My boards are flat and level, and have no issues with it at all. Overall I am very pleased with this planer. There are replacement blades available at Harbor Freight for $25.00.
The SOB is heavy, that's for sure. The dust collection seems to work fine. I've attached my small shop vac to it, but will need to figure out a coupler of sorts to go to the larger opening of the dust collector, OR, I'll just need to get a bigger shop vac (which my wife will "LOVE").
I don't think you can go wrong with this planer. I've looked at more expensive models, but for the price I'm really happy. But, like all planers, don't try and take too much off at once, go nice and easy and you'll have no problems.
