Hi all,

Hope someone can help me. I am looking for a USB Calculator / Keypad, with financial functions (+tax, -tax, MGN, Cost, Sell, Npr, n, PV, FV) etc. I have done numerous google searches, and have come across many adverts saying "full financial function", yet the products don't even have +&- tax, let alone any of the more complex functions. Being USB Keypad, i obviously want a keypad as well, and then the main reason for it - it must be able to send answer to PC... Does anyone know if such a beast exists?
