Sadly, the E-Flex is not directly available outside the US. InsideRide has not established easy options for overseas buying. Can’t hurt to contact them, but I have not heard of anyone successfully getting one outside the US at this time.
As to the price, I think there was one price increase, but that took place over a year ago IIRC (I would have to check my review thread, because I know I covered it in there, but no time to search right now.)
