I was in my neighborhood Sears store tonight and found the Craftsman Bis-kit System which will attach to most routers on clearance. Regular price is $49.99, now $9.95! Needless to say, this is less than the price of the slotting bit. This special clearance was in a Sears Essentials store, not a mall store. I have used this kit in the past and it works fine for installing biscuits. Get em while they last.
