UK and European EM prices are on the rise and have been for some 2 years. I think its much due to the prices being paid for SS and DM, the later especially, games falling out of most peoples price range. For example, Bop [Bride of Pinbot] prices are always 1k and more, 5 years ago these were in the low hundreds.

'Collectable' EM machines are going the same way where early Gottliebs used to be around for a hundred or so pounds, now most are a grand upward, in working order.

The trend seems to be folk in the retirement range are reliving their youth and treating themselves to a machine they played in their youth. In the UK, those in that range are generally quite well off and pay accordingly.
