My personal experience is that the more convenient the tool is, the
more likely you are to go to it. Simple issues like the chaff these
things create, make the vacuum attachment almost a must... for me
anyway. Then there is the speed by which the clamp operates, the
assortment of screws and the case it all fits in. The Master is
certainly worth the money.
The question remains how much you are going to use it.

Besides. it's Christmas. You wife might like one?
