We use Visual Studio Professional and we are quite pleased with it. We use Tortoise SVN, Visual VSN, NUnit and resharper. A combination that works very well for us.
Now we need to run load tests.
We looked at Visual Studio Team System, but frankly the pricing seems a bit lofty (obvious understatement). We are with a team of 6 developers.
I do want to 'get the best tools money can buy', still... Any advice? Are there alternatives?
EDIT: We develop a web application written in C#. We have been in business for more than three years thus we unfortunately cannot enroll in bizspark.
