Iv'e got a Monsta 420, and a Monsta 480, the 480 is like new but the 420 has a few missing fins on one side, and a dented end tank inlet/outlet port, These don't affect the cooling in any way. Because of the fins and dent the 420 is £75 all in and the 480 is £90 all in, I'll do them both for £150 incl P&P. I'm not sure of the rules regarding you not having access to the members market mate, so to be on the safe side, here is my EMail address and if your interested, drop me a message via that mate.
