My proposal will discuss input of cost data at length. The community will need to make some decisions on this subject. When you read the proposal, you will understand why.

I'm working on it now. It will be done SOON™.

Also, remember that Wikia's new VisualEditor will have a TemplateData function that allows the template to prompt the user for the desired input and also has some error-checking options. It's going to be amazing! :-D
