I added some extra features to my MZ-N707 by going into service mode and changing some EEPROM values from a tutorial I got from here. I enjoy using my MZ-N707 on a daily basis in my car, in my pocket on the go, and hooked up to the line in on the speaker set at my job. I've used a radio shack mic to record some phone conversations and some interviews I've done with local celebrities. Before that, I even used the line in to record a concert with headphones, yes a set of headphones. It's a very versitile unit. Don't pay more than $120 as that was the price mine was and it came with a bundle of components: tape deck adapter, remote, NetMD software, car charger, home charger, and rechargable AA cell battery. It's one of the best purchases I've ever made.
