The first thing I will do is set price aside and focus on the tool and why I bought the Domino.
I have orders for a few dining tables and chairs. I have made one prototype chair, while I have all the tools to make angled tenons etc., the time it takes me is ungodly. Having made quite a few farmhouse tables and benches for clients, it only seemed like good business to offer chairs vs. buying unfinished chairs to finish to match, but in order to make money I need to be able to make them in a certain time frame, this tool was my answer for that and it has performed just as I was hoping. I have also used it to make kitchen cabinet doors to inset glass (glass doors I always reinforced with a dowel in the corners or a spline) and has done a phenomenal job. All my previous benches and tables used mortise and tenon joinery, this tool will definitely speed that process up by at least 3-4 hours on each project.
The Domino is much beefier than it looks on the internet and is of quality, it cuts dominoes with ease and many different sizes; speeds production for sure. This tool operates just as advertised, the cut tolerances are perfect, for that, this tool is worth every bit of 5 stars.
The price? Insanity, as with all Festool products, they are not cheap by any stretch, but I think, just as with all of my tools, pick and choose the "needs" over the "wants", go from there. At $1400 for the Domino and a Systainer with a collection of Dominoes, I have a lot of chairs to make before it pays for itself, but, the time it saves me, is a little extra time that I can spend with my family or doing other things.
