i have a cor 20, it touched water once but otherwise has been in its box essentially new ever since. it didnt fit in the return section of my sump with everything else... i figured id save it incase i ever upgrade but doesnt seem to be any time soon. I cant offer a steal on it but if your interested i can try to make the price + shipping less than buying a new one. send me a pm if your interested.
