Like most of you, I used the great option 43 calculator from Shimi for years. Sadly, it only supports two vendors and lacks a few useful features, so I decided to create this new version. Feel free to use it whenever you like, share it and buy me a coffee :-*

Please keep in mind, that this is work in progress, so please double check the results and send feedback, bugs and ideas to stobies@codemaschine.de
