Another thing to consider: you may think you can, but you will not be able to resist buying more Festool bling after you take that first bump. You'll spend a few days wondering what got into you and hoping that nobody ever finds out you paid $700 for a circular saw and some guide rails. Then you'll use it. Then you'll start to wonder what it would be like to have a Domino machine. It can't hurt, right? After that, you'll become unsatisfied using your Shop Vac to collect dust. Months later, your wife will notice a huge dent in your bank account, and you'll have to make up a story about a distressed nephew or something. You'll come home one day to find a room full of friends and relatives who aren't there to judge you (although at least one of them won't be able to resist holding your Domino machine in front of your face and asking you why, oh why, did you spend $850 on an angle grinder?), just there to see that you get help.
If you buy the Makita, I can almost guarantee you won't own an entire shop full of Makita tools and assorted $75 plastic accoutrements a year from now.
They tried to make me sell my Festool, I said no, no, no...
