I’ve managed to get a hold of some of them 3-3.6v 10 degree Field of View, gradient compensated, and I’ll let them go at cost which is $25 each via paypal (normally $35+), and I’ll pay shipping. PM me if you want them, I’ve had good luck on arduino with some replacement IC2 and I’m going to port the tinyclr Software I2C code to use them and post the code back up.
I’m not making anything, but getting a large lot means I get a share in the low prices.
