There are a few local auction sites who sell lots from pawn shops, trawling the bay of course, and they have a differently labelled swedish branch as well. I'd say that one is still a pretty OK hunting ground! Picked up a 6105 some months ago "that needed battery replacement". Car boot sales are pure crap up here though ... :-(
Just the bay for me, I managed to pick up a seiko analogue digital (totally forgotten the model number noe apart from its a H something haha) from a charity shop the other week for £9.00 so that was a deal, boot fairs are crap here aswell.
I'd love to know where ramon from the bay gets his seemingly endless supply of old seikos from though.
