I've ordered twice from James Payette.
He has very good grading (he undergrades, if anything), and he has good
prices (which makes for a great combination). The problem is that on both
occasions, he couldn't find the more-expensive issues that I had ordered
from him. So, considering that I ended up getting only the few "filler" issues
that I added on to my order (as long as I was ordering other stuff), that made
for some very expensive shipping.
He really needs a more modern ordering and inventory system.
