same here, though i haven't used either, but i've heard better things about HR than about WV.
Tube-town in germany sells valves too- never used them, either, but their prices can be a little cheaper than in the UK. Depends on the postage costs, of course (for me in NI, the english shops often charge more postage than the german shops :lol: but if you're in great britain (i.e. the mainland) the postage might be sufficiently cheaper that you're not really saving anything).
