I'd second that - I buy all my Festool stuff from FFX - they always seem to be cheapest listed price. Maybe some other retailers offer discount if you have a trade account but they dont advertise it. FFX return policy is good and the free shipping is a bonus
+1 for Nuts and Bolts. I used to use FFX but after a bad experience with a faulty mitre saw switched over to N & B. Better prices, faultless service and they really know their stuff when it comes to all things Festool.
I now make my own, using long rippings, run them through the planer, round the edges, followed with a run over the spindle with a glue joint
cutter to create the ribs.
