I have found that the prices in the UK, especially London area, are about the same as in North America. Just that they are in GBP instead of dollars!
So in other words, thanks to Mr Bush....costs are relatively low in the US and Canada! So you want to earn your money in the UK and spend it in the US! Just an interesting example! A Triumph motorcycle, made in the UK is MUCH cheaper in the US than in the UK! Amazing what taxes can do, isnīt it????
Good luck!
