If you want to just ease into this without having to spend too much money, you could buy a set of the Bic Color Collections set. It's about $14 on Amazon w/ free shipping if your total is $25. If you want to try blending techniques or watercoloring, then try Prismas. Just buy a few and try it out and see how you like it.
