I am considering purchasing a MZ-NE410 as I found it really cheap from a friend of a friend and the unit works perfectly. He is selling it to me for 25 bucks with tons of minidiscs and a bunch of accessories like an arm band and several cases for minidiscs. should I go for it? will the latest sonic stage work with this player? thanks. ewwww wait...... I just found out that it has not line in..... crap...... no way...
