Credits component for Joomla 2.5

The website I am running and for which I want to get some components is a Joomla 2.5 website. I am looking for a component that will let my users buy credits, using popular gateways like paypal, credit card, bank payment, cash Following features are desired: - keep track of a users credits - provide an easy way for other components to let a user spend his credits (basically I will want to have several graphically customized buttons throughout my site in both content and components that a user can click. each of these clicks will deduct a number of credits from the user's account) - a easy and user friendly mechanism to prevent a user to spend credits when his account is to low or even empty. In this case the clicks mentioned above will have to be "void", aka the way to spend credits must provide this check. - an easy and fast way for the user to fill up his account - a history of the user's activity : when were credits added, and how many? when were which credits spent, on what and how many? - provide a way for components/elements to fill up a users credits, by adding to them and logging the reason and reference I have seen some possible candidates, but none made for Joomla! 2.5
