I just bought a Bravo II from a local vacuum store owner for $3.50. Haven't really used it yet, but I have heard it is a good machine. It is awfully loud though. I come across them sometimes at yard sales and stuff. What What color of bag are you looking for it to have?
I really would love the maroon, that is the one that my mom had, or the green which is the one my grandma used. However I really would take any one it is more of a sentimental item than anything.
