I used to use a press similar to the Harper - I don't know the brand
of it, but it was black finish, and it's commonly offered in places
like Rio Grande. It worked great. Very easy to use, easy to get a
good impression. We don't have one because of the expense - getting
the machine, plus all of the stamps, for what is basically a
convenience. But yes, they work real good, if you get into it.
