I think the Gina K Stamp TV kits are the best deal going. I've bought six or seven of them. They come with EVERYTHING! Plus, you can watch STV to see all the projects Gina made using the kit. It's $50, and worth every penny. They used to be monthly, but I don't think they come out 12 months a year now. Check the website to be sure.
I am thinking of designing my own A Muse Studio kits for customers, and I will definitely look back over my GinaK kits to see what she included, because I think she did everything right.
Unity's kit club was just the stamps, and one of the best deals in rubber, I think. I got my sister hooked on them, and now she's an Ippity Chick and flat out obsessed with all things Unity. **Waves to Noelle**
