I wanted to let you guys know, in case you didn't already, that Nonin has finally come out with a semi-affordable oximeter - now $99. And in such cute colors.

When I got mine five years ago, it was more than 3x that price. I couldn't afford it then or now but it was worth every penny. I should add that mine is still in perfect condition, with no problems.
Nonin is simply the best at this. So if you need one, maybe now you can afford it.
