Mike,
I spoke with the guy a few years ago, before posting the link back then on ORG. He wouldn't do the plates without month/year indentations before due to legal reasons, especially if you live in the state that you are trying to get plates for (his own efforts at wannabe screening). Maybe that has now changed.
Marcos,
I will be there in 2 weeks. Maybe we can go together and ask about a group discount for members? I'll watch him make a couple of sets of plates for me, too.
