Going by approximate weight and dimensions, ParcelForce quote me £56 ($90) (from 3 days, tracked), or £33 ($53) (from 5 days, not tracked) from the UK, but the Post Office will no doubt charge me something completely different. I'd suggest that you buy from the States if you can, but if no-one there has a spare Zero, you can have mine.
Lots of dust notwithstanding, it's in new condition -- never really used it, just needs a good dust. I'm happy to take £35 for it.
