It will depend on the pattern you are looking for? I have seen many that were advertised as Black Storms but they did not have that original pattern that was advertised. Pieces of the Ocean had a very nice one paired with a Mocha Storm on their last Auction. Also it depends on if they stay popular? Take the Maroon clown Lightning Pattern, that market has hit the wall with very cheap pricing. Yet True Black Onyx still bring a premium.
