[Amps] Protocase for amp cabinets?

[Dan Levin]

Protocase (http://www.protocase.com) appears to offer a turnkey cabinet manufacturing service that would be perfect for the price insensitive ham :-)

For around $300, they will deliver a full custom steel cabinet with all holes, ventilation openings, PEM's, etc. cut or installed, and the cabinet  powder coated, and silk-screened.

I wonder if anyone has used them for an amp cabinet, and if so what your experience has been?

Thanks!
