Ah, were in the same boat, im also still looking for an England wig as well xP
But yes I second Arda's Derek wig in Dark Ash Blonde; though you'll be needing to cut the bags a little (tho I think that goes without saying).
Thefivewits also has one; called Yosh Princely Hero Type, but whichever one you'd like go with
