Hi, sorry if this has been answered in a faq as it seems it has quite an obvious answer. Im a new guy and did check the faqs, this question should really be something taught in schools, its so basic. What do the letters I have seen after some minidisc recorder names mean? Eg I have seen ads (in uk websites) for Sharp MT899, MT899S, MT899S. They have similar prices, maybe they are the same? I have also seen advertised a MT20H, but the only reference I could find similar to it is a MT20, presumably this is similar. Surely some smart guy knows the answer, is it something trivial or does the letter S stand for sucks, letter H for horrible? Thanks very much Greg PS Sticky, what is that about?
