this is a bit of a old thread but I was thinking of getting another black box I don't have to build. Now that there is a decent setup pre built its a easier choice. but I have been thinking of using a whole house vaccum. this one is pretty beefy but it has the advantage of hanging on the wall and it is quiet so when I am cutting thin material I can ave it running without hearing protection.
