If I can just chime in with my thoughts...
I have just recently bought one from here
http://www.bakebros.com/14mm-domeless-honey-bucket-bowl-swivel-quartz-glass/
Here is a review someone posted that pretty much sums up what I think...
Good quality just like everything I've gotten from BakeBros, the bucket is old solid thick glass and the Quartz swing is 15.8mm and is ofz compatible, comes with 2 grommets so it swings smoothly, slight rubbing if it isn't centered when lowering the Quartz swing into the bucket, that can easily be fixed by centering the swing and being gentle, definitly worth the price after receiving the 1st I was so happy that I bought another one, the only downside is its hard to find the ofz caps for these.
Real problem is not having the carb cap available for low temp dabbing, also my swing doesn't sit at 90 degrees when full swung down, more like 110 degrees, so the product can pool in the corner of the swing bucket...this would be better if it sat straight...
If you can sort out those kinks and provide the carb caps too then I am in for a worked one
This is mine, you can see the arm doesn't sit straight...
This is what is looks like when straight but then it doesn't sit in the bowl adequately...
Hopefully this should help you out when you start to make them
