Late to the party. I have an older Unisaw with a dedicated box joint cutter setup which cuts nice flat bottomed joints. I use it for fast and accurate box joints but also rabbets, dadoes or grooving which doesn't require precision I'd preferably cut on the shaper. I end up using the Unisaw for these purposes a lot. I also use a router especially on plywood panels when its nice to be able to see the dado/rabbet being cut.
I would second the comments of others ... that $600 should buy a very nice used tablesaw that will likely as not come with a dado blade. I even see some Powermatic 10" and 12" in my area for sale at that price.
