Help finding a new yixing

I’m looking for help finding a new yixing tea pot for my wife. I suppose it doesn’t have to be yixing, but clay that can be seasoned. She’s a black tea drinker mostly western style and wants the experience of having a tea pot that can become seasoned and add the deliciousness of her daily tea. Since she brews somewhat western style the tea pot needs to be big, over 250 ml which is where I’m running into trouble trying to find one. They don’t make many that big. I’ve already checked yunnan sourcing and a couple other sites, but I’m looking for some suggestions for where to get a legit yixing or similar chinese tea pot, under $100 preferably. If you’ve got any ideas I’d love to hear them! Thanks!
