Dension 500 but it's quite expensive and even used on ebay the sellers are more than a little optimistic...but I suppose that's all relative to what people are willing to fork over. Another brand is Grom and they have the MST4 but you have to pay for each type of interface cable separately which once again pushes the price well north of what I would consider to be money well spent but once again the unit is worth as much as people are willing to pay...paying in South African Rands does admittedly contribute to my remarks about cost thereof.
