I remember you now! That's awesome! Unfortunately the shark only lasted about 3 months, but I'd like to try it again. I'm really not interested in any sort of trade with cash, but if you bought the tank in sure you would have any problem reselling it because you would have it at a lower price point. However, I would be willing to throw in my spare RSM tank. It's just a tank and nothing else, but it could be good to have in case of emergency, or you could always sell it.
