If you do not need edge work you can get by with just the thicknesser if you make a sled. Check out "turn my planer into a jointer", its a good work around if your space constrained but time rich.
[member=53578]travisj[/member] is right I did just that! But the A331 doesn't come until February 18 or 25 or so per Felder....so haven't tried it yet although I am itching to.
Thanks Matt. That Rockler unit looks pretty solid coupled with the 1 micron cannister so I'll be interested to see how well it does with your new planer/jointer.
