I got my Anton set as well. Since I bought two extra stock JVC batteries in the mean time, I really didn't need them. I hooked it up just for jollies, and I must say, I definitely will not be using it without good reason. It made the unit so back heavy it's quite startling.
I'm thinking about ebaying it unless I can find a reason to hold on to it. Does anyone know off hand if this setup will power the Firestore or a Varizoom monitor? I noticed there is an extra two-prong output on the unit. If that's the case, then I suppose I'll hang onto it just in case I get one of those items at a later date.
