Being that fraction imperfect I had tossed this aside to use on the ele a while back and never done anything with it. My jaw dropped a few minutes ago though at a price I saw offered for a 20/9% spells version, and seeing as mine is superior to that other one I am now chasing an idea of the true value (it's quite likely the bidder I saw is just paying over the odds, but my curiuosity has been piqued).

Cheers for any help you can give me.
