Well this topic may get moved to the Buy/Sell auction and reseller section in a while, but at the moment I think it's a genuine question about a JEM so I'm gonna answer it here.
The PMC is rare full stop and not many that I'm aware of made it to Europe.
I think the only thing to do is to mail the guy for a better/bigger picture and then make the decision. In truth if the swirl is terrible I think you'd be able to get at least most of your money back on it somewhere either at a store on a trade in (quote them production number and prices for mint condition killer swirls and then come down from those prices), or on ebay as many folks are happy just to get any swirl.
In your shoes I think in truth I would go for the PMC. There are lots of UVs out there, and a cheapish PMC these days is pretty much a thing of the past.
