I need a tape-recorder or something please help?

Go to Future Shop in your area, it has a very small pocket size digital recorder able to record up to 8 hours. It has a built in mic and runs with two AA cells. You can hide it in your pocket to record conversation as you like. Cost about $80 or lower . Copy the voice recording into computer via a cable from phone jack into sound card line-in. Then erase the recording memory and it gives back another 8 hours recording time.
