Good points!

Thanks for everyone's useful information on this, as always. You make
this a wonderful resource. In part because of the existence of your
expertise on this list, we are using the LPC instead of some other
manufacturer's products. I feel I have learned so much reading this list
for the last few months that I would not have found in specs or formal
documents. Thanks for your wealth of contributions.
