I've heard great things about the Thames and Kosmos science kits. We've been looking at a chemistry set for DS8. Any recommendations? They have the Chem 1000, 2000 and 3000. I've been deciding b/n the 1000 and the 2000. Anyone use them or have other recommendations?

Thank you!

We ordered the 1000 for DS for Xmas, but haven't opened it yet.
