Hi I was browsing this Linguaholic site for the first time yesterday and saw this question. Arabicpod.net has been around for seven years and I have been a paid premium member now for a full five years. I am a lawyer in the U.S. and am a casual learner, spending about six hours per week. Here is a link to the current cost breakdown: http://www.arabicpod.net/user/membership_comparison . So starting with the free, as everyone here probably already knows, you get just the beginner lessons (with user discussion). For a casual beginner, that may suffice for a while. The formula here is a few lines of fairly simple text, analyzed and translated with an 8-10 minute podcast. The "basic" user gets all levels and a regular .pdf transcript. The transcripts are excellent. There are five levels, beginner, lower intermediate, intermediate, upper intermediate, and expert. At $75 for a full year (and less for shorter periods), this seems like a very good deal. (I just purchased an Arabic book of synonyms at the same price.) For a five year casual learner, I find the expert level to be quite challenging, but all of the other levels are stimulating and accessible. The "premium" user gets some excellent additional features. First of all, there is additional premium content on the site (including games, videos, etc.). What I use always use are the premium audio embedded .pdfs for each lesson. Click on a button and you get the articulation for a line of text. Repeat until you learn it. I also use a graphic vocabulary checker, which comes with each lesson. For me, that extra content is well worth the $198 per year cost (and I also donate a small extra amount). The higher level content is phenomenal. Whereas at the beginner level you can only get a simple situation because everything requires explanation, the higher levels begin with very interesting contexts. There was just a podcast on a zoo in Argentina where users can feed dangerous animals. Other illustrative topics include floods in the U.S. state of Colorado; the Chelsea (London) annual flower show; the death of an Algerian singer. Many of the broadcasts include family, friendship. And yes, a bit of politics (but maturely focusing on learning the language and nothing really objectionable from any perspective). You can get this content beginning at $75 per year just with a basic! Anyway, as the seven year track record shows, the producers are committed. They broadcast from London. One, I think, is a physician doctor. They are outstanding teachers. And what I also very much like is that there is little advertising in their podcasts and elsewhere - they primarily rely on word of mouth for users. Good luck with all of your decisions.
