an alternative to a smaller planer is s larger drum sander. Wish I'd known that before I invested .... hard to justify having boh in a home workshop. The planers go thru blades, can be a bear to keep adjusted properly, and don't necessarily give you a finished surface ... you usually have to sand anyway. The drum sander will do all the work that the planer will do, plus give you a finished surface.
But .... they do take up some serious space.
