I think they're $250. Hasport/innovative have a cable actuated one and I think innovative sells a remote reservoir hydro conversion that semi-converts the cable system into a hydro. The cable actuated one looks like it could become a nightmare and get****ed up. And it seems that Hasport makes a cable actuated reservior system too. The cable conversion are $249 for the hasport system, but this only works for the d-series. And $149.99 for the innovative item, but that one works for the b-series motors only. Now the actual reservior systems cost $149 from Hasport but without the actual reservoir, so in essence its just an adapter. And $249.99 for the innovative item which looks fantastic.
