Am looking for £200 + delivery for mine (is what I paid for it only a couple of weeks ago before I changed my plans). It is not in as good condition as Phil's as a couple of the valves are missing, but I was planning on replacing the whole lot with Supertech valves anyway, so this didn't bother me!
I also have a full set of 20 brand new (still boxed!) Inconel / Blk Nitride valves for sale which cost me £380, can do a deal for both together if you are interested.
