Wonder if that price from Batterfly is including VAT, since I'm outside EU, I would like to buy it without VAT, since I have to pay VAT when it arrives here.
Btw, are you in UK?, if so, did you check with Dancap?, haven't seen it online yet, but maybe they have an idea about price..
And btw, Japan, voltage level there, is 100v?, they don't sell 220/230 volt versions in Japan I guess?
