Karen, I too have only seen the prototype. Wasn't the video of the Siamese ALgae Eater neat! I did not have the same trouble that Karen had starting the CD, and because of the general techy sophistication of the product, I have confidence that the production model will be more user friendly. It also has synthesized music. After hearing the discussion, however, I reduce my initial suggested "potential AGA order." Ten or Twenty is a much more logical number. It is really hard to say how popular aquarium CD's will be. In Europe, they do well. There are some presumably large ones that sell for $50 each. I am not familiar with any in serial format. Like Karen, they do not appeal to me. But there are different needs for different people. One application that I can see is for people taking them to their office. My office frowns on people using the INTERNET for personal purposes, but does not seem to mind if someone uses a CD. It may also be something great to accompany a lap top on a business trip... especially with a long flight! Since I am again ready to participate on the net, I can provide the AGA response back to Khew. What is your pleasure?
