Man this has me a little worried. Although there was some hope in there too. I have one of these on order with some juice. I ordered Monday morning and have yet to receive a ship notice. Not worried so much about that, at least not yet.
I just filled a j-tank. My first carto tank. So far I'm impressed. Otherwise, I'd recommend an evod or protank. I've had a good experience with an iClear30 too, but it's not as good as either the evod or protank.
Good luck with your tank problems/search.
