Reddit mentions of Divine Lotus Brown Gai-Wan with spout

I personally don't know where to get a good priced kyusu or extremely high quality ones and yixing teapots so I can't really comment there, but I've done plenty of research on hohins and other similar devices that range from 120 ml - 180 ml. I deliberately chose a hohin-style device or a spouted gaiwan over a kyusu or a small yixing style teapot for easy cleaning, smaller infusions, and so I could use it like a gaiwan minus handling the lid. Maybe a gaiwan would have been better for me, but I personally didn't have experience with one and the alternatives I found were inexpensive. I know that hohins aren't on your list, but regardless I highly recommend one or a similar device.

If you're looking to buy something without waiting for shipping, I highly recommend going to a Chinatown that sells stuff, Korean supermarkets and specialty stores that contain teaware, and Japanese supermarkets. I went to a Korean supermarket today and I was able to find a fairly nice small (I estimate 120 mL) teapot + set with a fine ceramic filter for $15. I didn't buy it, but the material feels like stone rather than porcelain so I imagine it would be great at holding heat. It came with two small teacups (probably 30 mL each) and a water cooling bowl that has a spout. I honestly don't know how easy this is to clean compared to a spouted gaiwan or a normal gaiwan in general, but this looks probably about as easy to clean.

Yuuki-cha sells several hohins including one that is made of unglazed clay and has a fine mesh filter.

One of the spouted gaiwans I was considering was this, but I honestly don't know why I decided against it. There's a green version floating around and it seems that clones of this product or maybe the actual product itself are sold on Amazon with a flat shipping fee.

In the end, I ordered a spouted gaiwan from aliexpress that looks nice, but it took 43 days for it to arrive. I ordered during a Chinese national holiday though so that definitely increased the shipping time, but I don't know how much of an effect that would have overall. It took forever, it was cheaper than all of these products ($13.05 with all possible fees; free shipping). One added benefit of this one is that the rice glass windows double as markers that you can use to approximate the amount of water that you pour through into the device. Overall, this specific spouted gaiwan appears to have a better pour than the semi-cheap hohins I've handled and it lets through far less tea leaves through surprisingly. The sencha I've used doesn't have that many fine particles/dust, but it seems that only a very small amount of them go through into the tea I pour out. I've seen comparison pictures of how many tea leaves/particles pour out from a super fine ceramic filter kyusu and I'd say that this spouted gaiwan pours exactly as much without using the metal filter.

If you decide to get a hohin, one thing you might want to be careful about is getting burned when handling one. When I first had hojicha in a cafe that provided a hohin + hot water, I ended up burning myself on the pot and in the end I had to wear some gloves to prevent myself from getting burned. With the yuuki-cha unglazed hohins, it appears that the small handles are thick and displaced enough to prevent you from getting burned. With the aliexpress spouted gaiwan, the little flap of porcelain is enough for me to not get burned even when filled to the brim, but you must be careful to not touch the rest of the gaiwan aside from the flaps and lit. I'm fairly certain that another way to avoid getting burned is to not fill a hohin/gaiwan fully.

If you're planning on pouring tea for more than one person though, I'd recommend getting a kyusu too, but I don't know much about them. All I know is that they're often either porcelain, glazed clay, and sometimes stoneware and that they have three types of filters: large ceramic filters, very fine ceramic filters, and very fine stainless steel mesh (non-removable and usually cover the spout only). I do not know much about where to get a nice kyusu, where to find affortable ones, and how much they can hold, but the largest one I've ever seen for sale was an 8 oz kyusu. I've seen some that are also 200 mL too, but I don't know the average or common volumes they're usually sold in. Probably the biggest variety of kyusu you can find are sold on yuuki-cha though. For both hohins, kyusu, and similar devices, I suppose o-cha sells some super fancy ones but they're fairly expensive.
