One does not simply pay a brass 200 pound an hour. It is folly.
There is a case for it. If you want a really specific look, specialised
services delivered really well by an acknowledged expert it might be money well spent, and I really can't see why that's not more commonly accepted.
Put it this way.... given choice of buying a Rolex watch for ten grand (not the most expensive model) and spending the same ten grand at two hundred quid an hour on WG's.... then WG's will get my money every time.
