Hello!
I decided to buy a new teapot (well... my previous teapot decided for
me, breaking into pieces...) and I was wondering if you could recommend
me some internet shop selling teapots of high quality.

All I need is:
1.To have an infusing mechanism like most of Yixing teapots (not basket
but a kind of netting just near the spout, inside - in the way that tea
can brew in the whole inner space of the teapot - I hope you know what I
mean?)
2.To be used for brewing all the types of tea. I will use it not at
home, therefore I cannot take three teapots. Just one for all.
(therefore probably yixing is not a good choice... unless I do not know
something)

Thank you for any advice, suggestions, names of shops!

Sincerely,
Milo
