I was thinking it may be because of the leccy voltage compatability but that seems a valid point K ,but how would it restrict HC sending it to the uk,after all they'll ship other joytech devices,and at nearly £30 quid dearer than HC i won't be buying one from joyetech,but it seems your probably right HC have stopped sending some joyetech products to the uk.
Joyeteck uk is owned by TotallyWicked,there address is TW old one before they moved to larger premises and they ship from the UK ,http://www.joyetech.co.uk/ is a 20% offer on atm,so works out just over £80 shipped.not gonna bother myself as its 11 watt/5v limit is a tad low for me.
edit:
err just seen the topic thread is about a healthcabin .so the above might not be relevant
