I'd LOVE to see the rattle an with a mouthpiece closer to the straight fab, out the top of the can of need be
I do want to be a helpful FCer and do my civic duty in the threads to stamp out combustion.
So...
I just became even that much more aware of the Chinese business practices and scrutinizing what surprise you may be getting in the mail. I want to educate myself on types of glass, especially food grade and heat resistant qualities. Want to be knowledgeable enough to have materials for scratch visual and integrity tests on hand. Perhaps pass that on too. 
The d020d from sunshine store is about as reliable as it gets in terms of DHgate class. Not my favorite for vaping because of the remarkably low drag, but an awesome piece. "Scientific glass" simply refers to any type of bubbler/bong/whatever that was created for its function, not for art--which usually means percolators (shaped water diffusers that make bubbles to make the vapor less harsh) and clear glass, because "worked" or colored glass is usually made by glass artists who are focusing more on the art than the function. I wouldn't worry about any type of danger from heat in this glass, no more than any American glass...The larger Chinese companies are not so dissimilar from the American glassblowing companies, save for a certain lack of QC consistency (depends on the seller, etc., avoid Steven & CCG) that is made up for by saving literally HUNDREDS of dollars. Adapters would be smart to get from the same seller for shipping purposes. PM me if you have more questions regarding glassA lot of people keep convincing themselves publicly on the EQ thread that they want to purchase a d020-D. It's like a fever I tell ya.
Can anybody recommend a reputable buyer, or any general do's and don't before I send them off?
If their is a more appropriate thread please advise. Otherwise I think it would be wise to inform yourself if you ever bought anything from china. Like say from ebay as another example, to at least be able to make a good visual inspection.
I am waiting for tax returns before anything. Would it be smart to buy adapters from the same dealer who you buy the main piece from? Is any of the DHgate sellers known for scientific glass? What is the distinctions between scientific glass and say borosilicate glass? Feel free to go completely over my head on the subject matter.
Would like to hear more about the practice of sellers trading items from other sellers to fill a request overseas. So you buy from glassblower A and get a piece from glassblower F who may use inferior product or have poor QC , all due to some family or back alley trade whatever. The glassblowers here are cohesive like that. Just wouldn't do business in that manner. Welcome to the East.
DHgate would be your cheapest option but for more local (USA) glass dealers are Thick Ass Glass.com, Smokecartel.com, and Retroactivesmokeshop.com are some of the dealers I've bought from.
In my opinion, I prefer 18mm for greater airflow. However depending on the size and function of your rig, you may not need 18mm. If it's a decent size rig that you need to clear in one hard pull, 18mm will benefit you more. If it's a small oil rig you'll be fine with 14mm.
