My first concern, I don't know what I'm doing and am going to get ripped off. I acknowledge that the write up about a pot on a website could be completely fake. No doubt. But I'm going with the idea that the more established online tea sourcing companies try to be honest, research their sources, and wouldn't last long in business if they ripped too many people off. Even after they see a product, what they actually receive could be something totally different and if the item is shipped form CN then its possible the online store will never actually see what is shipped.
Concern two: buying online. I don't have a 'local' source for tea or teaware.

Third concern: I've been reading about the modern clays containing stabilization chemicals. I haven't read any articles about 2 tea drinkers dieing from the chemicals leaching from a chinese teapot, yet. Are chemicals a big issue with the modern clays?
So far these are the characteristics that I would like in a teapot from highest to lowest: clay that doesn't leach chemicals, vendor that delivers what is listed on website, modern pot, handmade
What am I looking for? suggestions on vendors (us or chinese), types of clay that work well for puer teas, regions that make good quality, opinions if chemicals in the clay are really all that concerning
