I need to get a copy of VB for work, and I need to tell the purchaser what to buy, but I can't figure out the difference between the Visual Studio Standard Edition and the Professional Edition except that the Pro Ed costs $500 more. What is the difference?

What I need to do is generate a VB front-end to an Access DB, so I only need the VB language. Can the Visual Studio be purchased with all of the troubleshooting tools, such as debugger, but only contain VB?
