Thanks Simon, your thoughts pretty much mirror mine.
I think it's priced a little low as I originally set it as £180, but no bites so I have reduced it to £150, best offer I've had so far is £125.
I don't understand it, why would I let it go for £100 when the kit alone was £90?
Well, I think it's another form of proof for me that I am right in giving it all a break.
