Which Quadrilla expansion set?

Teo years ago I bought my grandson a Quadrilla marble Run. His birthday is coming up and my son asked me to get DGS an expansion set. I'm just not sure what to get. Has anyone bought more sets? If so which one.

I've bought a few expansion kits. The first one I got was this: http://www.quadrilla.com/article.php?sid=120 I've also gotten the switch kit (http://www.quadrilla.com/article.php?sid=43) and have added some extra parts. I really like the first expansion kit because it added more spirals, and those are always fun!

Thanks. That first one is the one I was considering.
