There is no such thing as have the money, every expense chips away from the profits.
Edit. I understand that it weighs against development time but that is a different matter than money in the bag.

Having used MySQL and SQL Server, there's not much of a contest. You can do everything in both, pretty much, but you can do it more quickly and more maintainably in SQL Server. The developer tools are all really good, the functionality is outstanding, it requires less care and feeding. There are plenty of cases where the added money isn't worth it. But your time has value, too.
