Help picking out a Christmas present for my girlfriend?

Hey r/tea. Greetings from a r/coffee denizen. I want to get my girlfriend an awesome Christmas present, and she loves tea (the woman has about twenty different loose leaf teas!) I thought I would be an awesome boyfriend and get her a boss tea set up.

I'm a coffee nerd, so I get it. Brewing methods make a huge difference. Different vessels matter. Different origins and terroirs yield subtle differences in the cup. I just don't know how to translate my coffee knowledge to teas.

My lady has a small teapot (not a yixing, it's got a strainer basket, and is made of a blue porcelain), a matcha set-up, and a bunch of in-cup infusers. No kyuusu, no gawain, no tiny clay yixing pots. I was thinking that I could get her a cool gong fu set up but I don't know where to go from there.

So where can I get a good-quality gong fu set up? We agreed not to spend more than $150 on each other for Christmas, though I am willing to go a bit higher and not tell her ;). I would need everything but a kettle (coffee nerd-dom means that I have a bunch of pouring kettles for pour-over coffee). What do you suggest, oh tea sensei.
