I had posted about this fireplace almost 10 months ago, and kept the contact info for the company. I called them the other day and talked to Andrew, who is a nice guy and a Cubs fan to boot. (He's much more confident about their chances this year than I am.)
Anyways, we talked about the issues of shipping to Sweden, specifically customs duties, VAT, and the like. He said they've sent many to Scandinavia. I told him I fancied a white one (as pictured) and he tried to talk me away from the white, as they only fit into certain interiors. Hmmm.
UPDATE: Andrew has given me the name of a contact at a local architectural firm to take a closer look at an installed unit or two. I'll report back.
