We are only talking about $200, split between 4 people.
I think the main goal at this point is to compare the different chips.
I agree that a comprehensive test would be great and should be done, but
doing this preliminary basic test is still worth the cost.
We can delay this forever, if we keep adding to the test plan.
My vote is to run this test on 11/15 and keep working on a more
comprehensive test for the spring.
