certainly the C125/6 needs domestic approval to be used on a domestic line. The FDA approves these products in the USA and we obviously have our own in the UK too. Technically, I do not think you will have a problem if you bought one for your own use, unless of course you 'cocked-up' an exchange and they tracked it back to you - might find you have a bill for several million punts.. LOL...
If you got your shares at .039 I would think you did OK, no-one is getting much better than that here (is that IR£0.039 which is 10% cheaper than £'s)
