I have the Festool original one, it is very useful to me and it saves my back as it is a reasonable height, it is truly multi function.
Quick to set up, a reasonable work area, side clamping, top clamping, strong, fairly stable, ideal for repeated square cutting on stuff like flooring, good for gluing up stuff using the dogs, many other things.
I get the CNC machined birch plywood replacement tops now as they are nicer and cheaper than the official ones (also lighter weight).
It looks expensive at first glance but its the sort of thing that works out quite cheap on a price per year basis and becomes worth its money over time.
