My ProVari will be here soon! It comes with the Protank, but I've heard it's not the best option for the ProVari. I've ruled out the ZAP, but I was told that kayfun Lite Plus Clone would be a good way to go. I started searching and am not sure where to order it from. Prices vary anywhere from $20-$60 from different vendors. Any recommendations on where to order this? Or an even better tank? Thanks!
