1. Hello, I recommend only getting the bundles that are actual branded clays, most of the no name ones will either be very oily and soft or very hard and not realistic to work with (but alsreviews would probably give more insight than I have into these clays).
2. Premo Pack this pack is about $25 either with prime or not.
3. Sculpey, this Sculpey one is about half the colors for $14 but there are a variety of sets of colors on that one amazon listing, so if you have ideas on colors you may want for projects you have a little bit of room to wiggle around.
4. I usually recommend Premo as it seems to be less brittle after baking compared to Sculpey III, but if you're just getting started it probably won't make that much of a difference.
5. Here are a few other good packs:

• Sculpey 30 pack on sale right now if this is still on sale I 100% recommend getting this one IT IS A GREAT DEAL.
• Sculpey 10 pack, this is just basic colors but since it includes primaries, you can mix them. Also on this listing their is a more neutral color pack.

Not sure how artistic you are, but I recently bought some clay and sculpting tools. Maybe you could make your own minis.
