I have this sytem and the Leigh D4, although I love the D4 I always reach for the vs600, I use it mainly for half blind drawers, I use mine to make about 40-50 drawers a month, I have a OF1000 router set up all the time for it. I am thinking of getting something a little more heavy duty, like the powermatic dovetail machine, but its alomost $5000.00 It is so easy to use and very accurate.
As a side note, I have the Dowel template and cutter that I have never used, if anyone wants it send me a PM with an offer.
Regards
Paul
