Mike - FWIW, I bought one of the vacuum pumps last year when I wanted to drain & refill the system, and have found it to work just fine. Yes, you do get the little bubbles, but I figured they were just coming in around the threads on the bleeder or the seal where the bleeder hose attaches. I did find that a little teflon tape on the bleeders helped to reduce, although not eliminate, the bubbles. Also, I make sure to close the bleeder before I relieve the vacuum on the system. I've bled the brakes with only the pump before each of my last 3 track days, and made it through 4 20-minute sessions each day with no noticeable fade. I think I paid around $40 for the pump.
