Greetings!

Yes, he is still making the kits. To quote his web site:

As kits become available, I will reply to each email request
on a first-come-first-served basis. You will only receive an
e-mail reply with ordering details when I am ready to fill
your particular order. These button sets are cast one at a
time, by hand, so there will be a delay between the time you
email me and the time you get a reply.
