Well, America has big wages if your title begins with "chief" and
ends with "officer". Rest in peace, American middle class.

I have an interest, but only for a handful. Will is right; the
molds will be the killer. I worked on a commercial product a few
years ago that used a two-part plastic chassis that was about the
size of a small book. The two halves were very, very simple...no
weird shapes, and not difficult for mold design. The "cheap"
aluminum molds cost us about $10,000 to have made, and the good
stainless steel ones (last much longer) were to cost about $18,000.
Molds for small parts such as switch handles will be cheaper, and
there's a side benefit to their small size: we might be able to
design one mold that can make several different types of switch
handles (PDP8/e-PDP11/20 style, PDP11/45-PDP11/70 style, etc) in one
shot. DEC didn't use that many different styles of switch handles.
There's still the front-end-loaded cost of having a mold cut, but
after that, the community would never again have problems getting
