October 24, 20224 yr Hi all, rather than invent the wheel has anyone got a pointer for a good spreadsheet to run cost calculations. The Solo one is OK but I would prefer to be able to use an automatic update system. I have seen some PDF files of ones people are using. Any help would be appreciated. I have also seen people offer their own version for use but many are from a while back so the users probably are on here any more?
