I want to forewarn everyone...I'm a geek!
I have an Olympus from target $59.00 and it's worth every penny! It has the usb cable, so you're able to upload files to your computer. I then change the file to an mp3 with a low bitrate. I download the file to my flash card which fits into my cell phone. I can then listen to the lecture with my cell phones earpiece.
When I had micro, I uploaded the lectures to my computer. Then at bedtime, I would open the lecture up with media player set on repeat. A passive way to learn.
That's lame that a teacher wouldn't allow recording. Time to go spy tech.You can get an olympus that will record longer, for maybe 70ish? That might be a better deal for the teachers that forbid recording. You wouldn't want your recorder to beep at the 2 hour mark.
