I have a small shop in the back of my large garage. As I do mostly furniture refinishing at this point, you can imagine the mess I make with all the sanding! As I would rather invest in a small (but adequate) dust collection system instead of fancy sanders with built-in bags, I need some advice.

Which systems should I consider? Money is a big factor, as I have to get approval from our household's finance chairman (my wife).

Thanks.
