Hi,
not an awful lot - I normally stick £15 - £20 on it (and the others in the series - there are several) for the fun factor, plus you don't often see them complete with tape.
I actually have a foreign version of this as well - French or Spanish, I forget which - and the mind boggles over what the translations mean!
I actually bought this new as a drinking game...
Cheers,
Malc
