The planer offering from Rockwell and Delta was and is ever changing. With very few exceptions these are all great tools. The stationary tools are heavy cast iron and only recently have been made in China. Some of the best were made by Invicta in Brazil, so don't let that scare you off. The portable planers came along after it became obvious that they weren't going away! Ryobi had the first and it really ate Delta's lunch for a couple years while they figured out what to do. Ever since then they have been ahead of all but DeWalt. Buy the newest version you can find. This is a smooth planning tool and is an excellent choice for thicknessing S4S lumber.
