Until you have some experience, as much as possible, buy pots live and in person, rather than over the internet. I have a pot collecting addiction, I have many more pots than trees.
Initially I only bought a pot if it was for a specific tree. To some degree, especially for lower priced trees, the pot should be near the value of the tree. A good tree, should have a good pot. But most important is the pot should frame or support the image the tree is creating. Wide shallow pot to represent a tree growing in a field, , a cube shaped pot for a cascading tree to represent the side of a cliff. Larger more massive rectangles for pines to represent the mountains they grow on. The image the pot creates when combined with the tree is more important than maker and provenance of the pot.
That said, there are pots that are works of art in of themselves. I have 4 pots by BeiGei (not sure I spelled it right) that I bought just because they had such an exceptional feel and quality. I have had them on a shelf in my living room for 40 years without ever wanting to put a tree in them. They are appreciated just as they are.
Most of my pots came in to my collection with specific trees in mind.
I've been "doing bonsai" since 1979, I set aside enough money to buy one or two or more pots a year, each year, every year. So after 45 years of acquiring pots, I have quite a few, but i usually did not buy too many in any one year. I'd say for American potters most of the pots I purchased were between $25 to $250 with the average around $45. I had a chance to get some good YiXing pottery from an importer from China. This was not the Temu junk, but serious quality that rivals Tokonome. I have over the years bought a number of Tokonome pots, from its various potters.
I'd say more than 50% of the pots I own are USA made. Sara Raynor is a friend, so I buy a pot or two from her every year when she comes to the bonsai show in Chicago.
