Well, I have had the incredible luxury of being born in Finland, so state/municipality pays everything. Insulin, Glucose-test-supplies, Doctors. I truly fell sad when i hear what US based persons have to go through. Though, i suppose i pay it in taxes :)

About devices.. The first Glucose-test-device (what are they even called in english) took 5min to process the results. Current one is 5sec. A massive improvement in both speed and accuracy in these things.

I hope a good non-invasive device is developed, though i'm not sure it is essential, for me anyways.
