I saw a few posts below, and I thought I'd add my company to the list of online engineering continuing education providers.  I basically started the company to give engineers a more affordable way to earn their continuing education credits.

We provide the Florida laws and rules course at the lowest price on the internet.  We also have a really good selection of ethics courses.  We also offer courses in civil, structural, mechanical, geotechnical, green/sustainability and architectural engineering.

We are approved providers for the Florida Board of Professional Engineers, North Carolina, Indiana, and Lousiana.    We will soon be an approved provider for the state of Maryland as well.    The only state our course are not accepted in is the state of New York.
