Hi OutlandMetro,
I know that you already have decided to pass on Minidiscs but I juste wanted to give you my experience of it.
I used to own a Sony MZ-R900 a few years ago (actually I still have it), I bought it brand new in a serious shop. So I spent over 200€ for this top of the line player/recorder.
Everything went perfect during about 8 month and it then began to stop reading my MD's or it just kept on searching for the tracks during a long time, 5 and more minutes.
I loved it because of its compact size, its good sound quality, the possibility to record, and the fact that MD where just cool because not many people were using them.
Let me tell you a story which I found really cool after it happened:
I was sitting in the bus, listening to Supertramp on my MD player. After a while, 4 guys came near me after I had taken it out of my pocket. Actually its little size and the blue color of the Mg housing made it clear that it was a highend music player. I knew straight that these guys were interested in this thing, but not in a kind way if you know what I mean. Their behaviour was a bit agressive and strange. So I showed them the thing and one of them asked me if it was a MP3 player and if he could take it in his hands.
Shaking like crazy i just told him: "ok, have a look if you want" and at the same time I let him know that it was a MD player.
They all looked surprised, he put his hand away because at this moment he wasn't interested anymore because it wasn't an MP3 player, LOL.
They went away and got off the bus at the next station.
I was just like: "WOW, that was close and I'm glad to own a MD player instead of a crapy MP3 player which I wouldn't own anymore right now!!"
That's why despite the fact that these players are, in my mind, very fragile because of their complexity, I still find that they are really cool because of their little size and the fact that few people know about them and are interested in them.
I would just say that if I were you, I would also have passed on Minidiscs because of the price and their fragility.
After having thinking about buying another one, I eventualy bought a used Sony D-NE10 Discman, because I thought that it would be a pitty to leave my CD's unused at home as backups. I don't need to record so I don't have the same needs as you.
PS: the MZ-R900 had a separate battery holder for one AA and I used it a lot. Like you I hate to feel traped with those special batteries (gumsticks and whatever...). I love the fact that you can go in any shop to by AA's and just listen to your favorite music almost anywhere in the World. The D-NE10 also has a AA battery holder and it's already plugged in!!! :-)
