Do you still remember your very first cassette recorder? It probably in the trash bin right now. I thought this kind of gadget is not being used anymore because of the latest gadget available in the market. We have iphone, ipad, ipod and other electronics to record voice, interviews and the like. If your work demands the use of digital recorders, then you should check out thesource.com. They have wide selection of digital records, voice recorders, portable cassette recorder and much more that looks so handy. I remembered when I was doing my self-review for the board exam, I used cassette recorder to read the questions. I would say that review technique was very helpful.
