That's right. If the machine runs the protocol, we only know that the
MCU is working. We have no idea if the heat block is working properly
or the temperatures are displayed accurately. The machine could have
moisture damage or a cracked heat-block, for all we know.

$600 is a lot for a single instrument. The coffee cup PCR is a good
one, at half the price. If we use an innovative alternative to
machined heat-blocks, like Simon's suggestion, then the price is
better. Maybe the OpenPCR folks should build a budget version, based
on that?
