I have one Edirol R44 and I am satisfied with it. The Time Code feature is not there. So I am thinking to buy Edirol R4 Pro or Sound Devices 744t. I would like to buy 744t if I can find used one in good condition. I am from India and I would be grateful if I get any good advise from the experts about the choice of buy between 744t and R4 Pro.
