Check this guy on ebay, he sell dual doser for under $100. I use a dual one for my 2 part B-ionic and a single one for my top off.

\Nice doser. Does it have the ability to dose the two parts at different times? B-Ionic 2 part should be added at different times to maximize efficiency.
That doser is a very nice (and priced right) reconditioned peristaltic pump.
