Summary: A great purchase. Feel lucky to have found it. Smooth transaction. Highly recommend. I use this recorder every single day. Takes a licking and keeps on ticking. You will not be disappointed with this one.
Summary: This recorder is very sensitive and you don't need to sit in front of the lecture hall in order to get good sound. Excellent voice quality. However, I am concerned about the $300 price here. I paid about $120 from Best Buy last year. Must be an error here, as Amazon's prices are usually very competitive.
Summary: I love this cassette recorder. I never record on it - only listen to recorded books, and it's perfect for that. The sound is excellent, battery life is good, and it has switch to change the tape direction. Wish I'd bought three.
Summary: I bought this recorder because my 5 year old Sony TCS-100DV broke, and because it looks that nobody but Sony makes tape recorders with autoreverse. On the plus side, this model uses AA batteries instead of AAA and it's a lot cheaper; on the minus, I miss the battery indicator.
Summary: I bought the 500DV about 3 years ago and have used it everywhere for everything. I made tapes. I listened to Books on Tape. I used it with headphones; I listened to the integrated speakers. I played it in hotel rooms, airplanes, the desert, the snow, on long drives, while doing carpentry, while changing my oil. It's been dropped, sprayed with water, subjected to sawdust, dirt, and hundreds (yes, hundreds) of public library cassettes.
