Well I believe you can send a cheaque to Projump --tho you have to wait for it to clear b4 dispatch. I believe Carma saw some rather dodgy ( and illeagal ) versions sold in a Kent market a day or 2 ago --but you seriously do not want to go there.
Oh and being the pedant that I am, you state you want to know of a shop 'near kent'. Do you mean you specifically do not want to purchase from a shop in Kent? Cos I have just been vaguelly told of 1 in Reading ( well on Xchrimbl Day my sister said to me 'We saw a shop that sells your things in Reading last week')
