i've been out of minidisc recording for a couple years, but i'm sure there are some people on the board that can speak from personal experience on which models they prefer.
frankly, i think most md recorders are about the same these days...just make sure it has the features you want on it, and for the sake of pleasant listening don't use and of those lp modes to record, you're going to seriously degrade your quality that way.
while some people frown on the compression scheme of md, it really is not that noticeable unless you have a very distinguished ear and a nice playback system, so if it sounds okay to you, don't let anybody tell you not to get it because of the sound quality loss.
the reality is md is affordable, convenient, and very portable and stealthable. it is a great way for someone to start getting into taping without plunging head first into what can become a very expensive hobby.
good luck! and keep asking questions!
