It would be 100 dollars. 40 dollar postage. 400 dollars to buy one (assuming they take an offer). That's 540 dollars or £320, roughly.
If you want a good deal in the UK, ask Ed (Nugent) he had them on offer on here not long back
FYI - i just offered $400 and it was countered to $449. They have auto reject on under $400 so use your offers wisely. I'd go $410 to start if I were you, you may then end up lower than I did - which I declined in any case
