From what I understand from my conversations with Walt Pearce, they only made about 10 balancers and all had to be pre ordered. I don't think there are any more available at this time. I am still waiting on mine from Walt. Apparently there was a problem with the prototype and had to be re worked a little. Hopefully mine will come this week. Its only been about 4 months since he got my 4 bills geesch!
