Best way to get it made in the UK would seem to be to buy one and support the movement so that they can continue pressuring the government to allow them to make them in the UK.

I mean really, who are you protesting against? The government, right? What does the government care if you don't buy a $25 gadget?

I would pay more than 25 GBP were it made in the UK. And this isn't a movement -- it's not "occupy".

Why not? Are UK residents more deserving of a job than Chinese?

if you have an ounce of patriotism as the inventor, yes.
