7th Floor do suck for international shipping. I really appreciate it when US vendors are flexible and sensible on shipping. It's just infuriating when they refuse, even when requested, to send a $5 part by anything other Priority or Express, as 7th Floor have done to me. First Class International FTW!
I think the UK distributor for 7th floor is
euvaporizer.com, at least it was. They could help.
Also
market place brighton in the UK has them, but they seem to be the old smaller ones.
Otherwise
Lacentralevapeur in France for the fatty and saturn.
There may be more.
