This little glass teapot was $6.99 holds about 200mL
and has a glass strainer built into the spout
This is a very small yixing pot, 60mL, $5.99, probably not the finest clay, but highly functional
also with a strainer built in
and this is the strainer built into the kyusu from dens ($50), which holds about 6 oz; the strainer is finer and much larger than the others, and drains finely cut senchas very quickly

And for stuff that gets through the larger straining holes in the chinese pots, I use these funnel strainers ($2.99) on top of the cup or thermos
I bought the kyusu online because my local chinatown tea shop only had some with a metal strainer inset. I've not seen anything as simple and inexpensive as the other stuff online.
