I came across this Google ad in my mail: http://www.byki.com/

So, I gave them my junk mail email address and they started sending me lessons.  I started with the flash cards - easy!  "I know these!"  Then they started presenting them backwards, giving me English and asking for  Russian in multiple choice (I think).  Neat.  "I can do this."  Then
came the hard part: Type your answer in Russian.  I thought I had it right but left off the soft sign - WRONG!  Man!  Some of these Russian words are hard to spell!  (They give you a little Russian keyboard on the screen).  By the time you learn to spell these - you ought to have them down cold!

So I bought it.  I haven't used Rosetta Stone but this was a fraction of the cost so I'm going to say it's a pretty good value.  You can really manipulate the lessons and they way they are presented.  Incidentally, I also recently purchased Berlitz Ear Worms (I know - ewww!) and moved to my MP3 player.  Byki had podcasts too.  Tons of them!  I was shocked at how many podcasts there were!!  They already had a lot more content than most beginner language series.  It's an amazing value - and very portable.  I wish this was one of those sites I could profit off of sharing ideas like that!  :-)
