I have Delta 22-580. It provides very good results, minimal sanding needed, I usually start with 120 primarily for leveling joints and covering my screw-ups:). I've ran about 200 BF each of red oak and rock maple throught it. I've done some cherry, pine, pecan, and poplar as well. I do get some tear out on the rock maple, but I put it on the finishing speed, and tear-out all but disappears except on really nasty grain.
However, the dust collection could be improved. The hood tends to plug easily and it does not get all the big stuff. Also, it hangs down slightly and interferes with the wood coming through. The outfeed rollers generally push the boards past it. On hard maple, it is so slick, the outfeed rollers spin on the board and you have to "help it" get through the cutter head. I've only had this problem on hard maple. Oak, cherry, poplar, all seem to go through just fine. I think this model has been updated and they improved the dust collection. I would buy the new model of this again or look at the Dewalt if getting a lunch box planer. Hopefully my next one will be a 15" to get the steel serated rollers, better DC, and induction motor. The universal motor is very loud, I wear good hearing protection when using it.
