C# Editor Question from Newbie

Question

Hi, I have taken classes with C++ and Visual Basic and am interested in learning and programming with C# to create some programs involving stock market research and trading. I bought a book that explains programming with C# with Visual Studio .NET. However, I did not know the price was over a $1000 dollars for the program. Are there other good program developers besides this? I found Antechinus on the web for $50 but it has only a limited description. Thanks.
