I have had this spreadsheet on my aging iMac for a long time now. It has BTC prices (USD, GBP, EUR, SGD (Singapore Dollar), and 4 metals: Gold, Silver, Platinum, and Palladium in both grams and troy ounces). Difficulty is from the Internet, as well as target (for solo mining (blocks)). It accepts hash rates in both mh/s and gh/s.
I worked on this during last summer's vac and am only asking a small price of 0.06 BTC for it.
