Don't want to lose these sites!  All free.

Word2Word is a collection of language-learning resources on the web...many languages, many formats...lessons, games, newspapers, blogs, and more.

byky (before you know it) has flash cards and lets you hear a native speaker say the word.

FSI (Foreign Service Institute) courses have been developed by the US Government for diplomats, soldiers, and other officials, and are in the public domain. Many recordings are from the 60's and 70's, but the material is still good and effective.

Livemocha has lessons (the free ones should be all you need), but the plus here is the inclusion of a social networking site so you can practice your skills with native speakers. You can also help those who are trying to learn English. It says it's designed for "all language goals and all skill levels." I might have to think about this one...

BBC Languages will help you learn a language in 12 weeks with lessons and weekly e-mail tips. Audio and video courses are available for several languages. Instruction uses conversation.

Does anyone have comments on any of these or other suggestions that work well?
