Steve,
The one I use belongs to a friend.....it's a Dewalt but a small bench model and is a true thickness planer. He has also let me use one like you show in the link and they work very well also. Biggest difference is that your hand pressure can make "waves" if ya dont take it easy on speed etc. But as far as making things flat it ought to work great. If the blades are adjustable set it for as thin of a cut as it will allow.
