Thanks Eric. Yes the site has not been updated since like... forever! I sent him an email and inquired as to what he had available as well as telling him what I was interested in. He sent me pics and I went from there. Definitely a tough guy as far as getting him down on price. At least that was my experience.
I also have my own stock in a growing bed but it is still a long way before looking anything like these.
Funny Al, as I was posting these I was also thinking about your own "pigs"
I believe the first two are standard green maples or at least look like they are to me. However, the last one is not. It has deeply incised leaves. I think it may belong to the Matsumurae group of maples. At any rate it does not look at all like a straight up A. Palmatum.
