Here is the deal. I have a large number of chairs to make (12) and do not want to cut 240 M&T's the conventional way. I want to make profit, not tenons. I can either convert the G0540 into a slot mortiser (locktite on the jacobson to account for lateral movement) or buy a domino. After cutters for the G0540 and all the festool bells and whistles I come to about a $850 price difference. Both machines will do the same job, and I prefer stationary machinery for precision. Is that an oxymoron since I am talking about a grizzly machine? Anyway the only plus I see to having the domino is the ability to take it to the work instead of vise versa. Is that worth the price difference? Anything to add?
