I love Jessicurl too!
After about 8 months of CG, my hair is finally starting to look really good, though I really need a good curly cut, which I'm going to take care of next week. I've tried my fair share of products, and I must say I like Jessicurl the best.
However, I don't buy them directly from the Jessicurl site, I buy them from Curlicious.com, as the shipping is significantly lower there. The only drawback is that you can't buy samples and trial packs, just the full size products.
