Logo for Modern Industrial, new e-commerce site

Description of the organization and its target audience

This is a new e-commerce website that is not yet live. As such, we
have no established color scheme to match. I expect to launch it in
about 2 weeks at http://www.modernindustrial.com/
The site sells industrial products to B2B buyers. Products include PVC
piping, electrical panels, HVAC components, pumps, fittings, etc. Most
is used by large commercial buyers either in manufacturing or other
industrial uses. The typical customer is male, 40-60 years old.
I would like the logo to be fairly simple and clean.
