Since we are getting more than 4 boards, I would suggest Andrew's recommendation of PCBcart.com as there may be a chance the design is flawed (low probability) but it still lowers the investment for everyone, though the differential does not bother me.

Hi David,
Yes, there has been crossover in the posts (sorry, I should really scan
ahead before replying.)
I was going to order ten boards in any case and hold onto the extras
myself (so no need for anyone else to get more than they've indicated
already.)
I'm happy ordering from either place myself too so will scan through my
email and see what you've all decided.
Thanks!
Todd
