Hi onix505,
I am sorry that you feel dissapointed however, if you like the effect I suggest you visit the PropDog site for a UK currency gimmick which will cost you an extra 15 Pounds:

I understand your frustration with not receiving the UK gimmick however, due to a not high enough demand, we can't offer each customer a gimmick matching their currency.
Hopefully you'll get yourself the UK gimmick and try the effect out a few times.
I am sure you will love the reactions and if you do any paid gigs, the investment should come back to you in no time. :)
Lookinf forward to your feedback.
All the best
