rdesigns, you are more at the leading edge than you give yourself credit for. I wandered into my local dealer today to buy a Festool trinket or two and found this thing on the peg board. It so happens that I was spending the day doing just that using Rick Christopheron's more elaborate product, so I asked the fellow at the counter about it and he had no idea, not being a user of the product. We looked in Festool online and there is no reference to it.
I searched here and found two references - one that was hijacked to promote Rick's product [huh] - and this being the second. As mentioned, I was in the middle of end-mortising a bunch of 1" x 4" stock for use as side skirt rails between two legs. At $25, probably one of the least expensive items in the Festool catalog, I grabbed it.
For simple, end mortising of skirt rail ends and base board sides, etc., its two preset paddle stops are an easier to use, more efficient operation, than the $120 alternative with its four steel stops that tend to flex and/or get in the way.
