I'll throw my hat in to contribute to the pan-Benelux expansion!
You often see collection-only auctions here in Belgium. They'll typically either be at ridiculous Buy-it-Now or starting bid prices, or starting at a low price and hardly climbing from there. I guess ebay hasn't really taken off over here yet! My €200 Merckx Ti and €50 Record-hubbed wheelset to wear with it are clear testament to that, and also the €55 Peugeot PX-10-a-like, and ... anyway enough gloating ...
I can (and already have done) cover pretty much anywhere in Belgium, though Luxemburg and Limburg provinces are a bit of a stretch. Anywhere in Brabant, Namur, Hainault, or East Flanders is easy. West Flanders, Antwerp and Liege provinces are a bit more of a stretch, but do-able.
I have a Parcel Shop right next to the office and find that GLS offers reliable and cheap shipping to pretty much all of mainland Europe.
Cheers,
Gareth.
