Get the Kreg system!!!!!!!! I was an idiot for not getting one until recently. Face frames and cabinetry in general is seriously simplified!
You don't need to get all the fancy clamps. You can use regular clamps just fine. Also, get a big set of the 3/4", 1" and 1-1/4" screws.
I see they have the screws in coarse and fine thread. Which are you using for most of your projects?
