MagDrive Ventri Setup?

[BlazinNano]

Does anyone know where I can buy just the needle wheel and the ventri setup? I have an extra mag3 that I was gonna hook to an extra skimmer for a friend. All I can find is the complete pump. Or is there another way to convert one?

I've modded a few by the very fancy method of simply sticking a bit of the airline into the 'intake' part of the pump, without modding the impeller or intake or anything. Try it out and you'll be surprised just how fine of bubbles it's able to produce- not as good as a needle wheel, but still pretty effective.
