Can anyone provide me with a digital drum kit/set?

I am looking for a digital drum kit for SolidWorks, but IGES or STEP is also OK.

I really doesn't matter which one, as long at all the dimensions are correct! But, a Roland TD20 could be nice...

PS: I have a 3D model of a set, but it's in c4d-format and I am not able to convert it. Anyone who know how or could do it for me?
