I did some fine tuning and came up with a rather interesting way of keeping all of it to one class to represent the money. This is an example of one of the sets, the others look like this with a few changes. At the moment if it tries to be set to something below 0 it will take it from itself and if necessary work it's way up first and then down. I haven't been able to test this yet but I would love it if you could take a look at it and see if there might be a way to cut it down some more (The original was hideous!) Hopefully if I keep it to this one class then I could finally take a step forward and continue adding more and more to the database.
