Vacuum, speed bleeder, or..what's the best one man bleeding system?

I have sold and used the Mighty Vac and Vacula design bleeders. They provide vacuum at the bleeder and the only way you can introduce air into the system is if you have a leak somewhere or you run the master cylinder dry. (they have reservoir bottles to keep the master full in most of the kits) These are very handy especially if you are bleeding new lines. They are $100+ though and you may not use them often enough to justify buying it. They are also handy for sucking the master cylinder dry if you need to replace it. It helps prevent brake fluid spills on the paint.
