Okay, NOW I see what you wanted Stu... Nice problem. :)

What you need (and the other folks) is to re-work Brice Hornback's business
model and get the PSIM-1 back into production:

It was an AWESOME module, but Brice had (and still has) some serious
business issues and only delivered 50 or so in 3+ years.

I'm lucky enough to have one, and it could easily handle what you're
looking for.

Deiter - maybe you should contact Brice about acquiring the rights to the
module and re-manufacturer it :)
