Homebrew PCBs

Hi,

Problem with enclosures - I find the enclosures I want, but they turn
out to be unavailable here in NZ.

Plenty overseas, but at the price of inflated handling/shipping charges,
which for small quantities blows the price out hard.

This makes me wonder about taking a DIY approach.

Not wanting metal, or folded plastic etc. Needing a process which can
produce reasonably attractive plastic cases.

Has anyone had success in this field?

If so, can you point me to any good sites for learning?

I'm thinking of starting with perspex (called 'pexiglass' in some areas
I believe).

Cheers
David
