Guys from my perspective this specifically for some guys that want to replicate their MFT Festool tops. It's for a very specific person that is in the Festool System, uses the MFT set ups and doesn't have the time or ability to make tops or the jig to make the tops themselves.
Good luck trying the old school methods or drilling one hole at a time, that's a joke and anyone that says that does not understand what this is for. Even the smallest of these tops have 84 holes perfect drilled and spaced and both spacing and hole size can't vary by much more than .5mm or they wont work very well. Getting the precision needed for a large MFT top and then be usable later with the Festool products is not as simple as some of these comments make it seem.. The entire reason these jigs exist is because so many have tried and just given up becasue of the time involved or crappy results they get. Then they are forced to pay the high expense for a new MFT top. The layout for the MFT tops is very specific and so is the hole size, about 19.8 to 20mm and 96 mm spacing in every direction(mine a perfect 19.85mm and 96 mm spacing). Who wants to do that one at a time even if they could? My large top has over 360 holes perfectly spaced and each hole is exactly 19.85mm , this is CNC work in 2017.
I have several CNC and I can tell you right now the only way I ever made these tops accurate, precise and fast was with the CNC and even then I have purchased new mft tops myself.
So yeah if you want to take the time to make the template I get that, but even then you still wont have the nice machined parts with this kit that are designed exactly for the MFT holes and layout. This kit will be worth it for many people. For the guy who is making 40.00 an hour at work it is hardly worth his time to make the tops or even make the jig, he may as well purchase this so he can get to work on his hobby sooner rather than waste time remaking his top. Plus, this gives the ability to make small jigs and tops out of MDF using the hole pattern that works with the Festool layout, like tool box tops for clamping, etc.
This version is better then some where they charge you 189.00 and the jig only lays out one hole at a time!
