Errrr... You really, really don't want to go on international eBay to get an English razor. eBay UK is a far safer bet. The FAQ here has an entry on optimising your eBay search. Apparently, you want to eliminate the usual suspects from Asia first.

And no, Wade & Butcher would not be high on my list of English razors to buy. A Sellers, however... There are many very nice English brands out there whose prices have not been hyped through the roof. Happy hunting.
