Joel, it's a bit rich for my blood - but let me also say this: Festool makes some very nice tools, but isn't it just a quick way to do loose tenon joinery? If I needed something like that, I think I would first look hard at something called "Beadlock" - I've not used it, but feel confident someone on the Router Forum can tell you everything you would need to know about Beadlock, as well as the Festool Domino. I have an old, yet very effective dowelling jig that I've been using for quite a while and for my needs it is the best I've seen. I'll take a shot of it and get some info on it for you and reply again with that stuff on this same thread!
