Hey MMZ, you missed the boat
I designed and built a few of the max1668 circuits and sold them on ars technica, I guess I should have made more. If you want in on the 2nd production run, let me know

(You'll have to scroll to see the finished product - don't be alarmed by my hand-made one at the top o the thread).
I was selling them for $39 shipped, which includes the power and signal cable and 4 probes.
