For the last few days I have been testing
this.
And believe me it's wonderfull. Its' a lot eassier then making MSBuild or nAnt files and I believe it is even more versatile.
It is especially usefull if you have no real person in the team that is resmonsible for the builds.
Finalbuilder is ideal for all you .Net building works.
Now let's build.
However it not free.
