Good luck! Sorry to hear about your loss... Pawnshops never really took off over here in the UK. Instead we have chains such as 'Cash Converters'. I call them 'Smack Converters'. Be vigilant and search those stores. I don't know what the process is for trading stuff in, but if they have to provide I.D. of some sort, or they are stupid enough to give their genuine personal info you may just catch them too. Seek and ye shall (probably) find! You have serial numbers etc?
