Could those using tea boats share your source if you're pleased with it? It would be greatly appreciated

I've been inactive here for a long time so good to be back. I scanned and searched previous topics and just couldn't find what I was looking for as most links were outdated and couldn't find much. My eBay and other resources I used years ago aren't coming up with much except DTH has one option. I'm on the search for a few great bowls to rig up my own but need something for the present while I search for just the right thing.
Thanks in advance!
