Tandem Tour of Europe... help!

Hello everyone...
apologies for this obtrusive or off-topic post, but we were wondering
if anyone in Europe could help a few tourers out. We are 2 Canadians
touring Europe by tandem. A few days ago, it was stolen in Northern
Europe. We still have 1/2 of our trip to go and are hankering to get
back on the road. Does anyone know of any used touring tandems that
are available in Europe? We're willing to do upgrades if necessary,
we're just keen on the tandem frame. A store or a friend maybe?

We are currently in Stockholm, and plan to continue cycling somewhere
near Prague (we'll plane/train/bus to Prague or anywhere in between to
pick up a bike if we have to). Cheers to anyone who can be of
assistance.

Thanks again,
Brad Zarikoff
