Looking to upgrade from my 12" Delta lunchbox planer to a decent stationary unit. I have looked at some of the popular brands.......Grizzly, Jet, Powermatic and they all seem to be stamped out the same factory Looked at the Delta 15", and it seems to be good unit but also imported. I dont know if I really need a 20" planer or if the smaller 15" would suffice. I do like the idea of having the extra capacity just in case of a wide glue up, but dont know if this justifies the extra cost of the 20". I dont want to spend more than $1500 and all of the above 20" planers come close to this price. What do you all think? 15" or 20"? Brand preferences?
