I've ordered glass and other stuff from DHG and never had even a hint of a problem. I figure that if there were problems with credit card or personal data theft or misuse, we'd hear and it would destroy their entire business.
For what its worth, I recently got a bubbler from Sneaky Pete that both does the water job quite well and wasn't that expensive, $64US, the Buzz, Honeycomb Perc:

You also need a way to attach the vape to the bubbler. Having broken my own Crafty using a glass water pipe adapter(wpa)--and I'm far from the only one--I strongly recommend the silicone Crafty/Mighty wpa from Delta 3D:

Re: Old!: I'm in my seventies. Been using dope in joints and pipes for nearly 50 years and was formerly a cigarette smoker. Stopped smoking cigs 7 years ago and been vaping weed exclusively for four years. But my lungs are still sensitive. I've tried a great many vapes and owned more than a few: the internal cooling path of both the Crafty and the Mighty are the most effective, though neither is at work when hooked to a wpa. In my search for wheeze and cough free vaping, I've tried connecting my bubbler to the cooling unit mouthpiece, but I can't perceive any difference from connecting to the oven with the wpa. Hope this all helps.
