I've been using a stargate for about 2 years now. Mine also social smoke.
I found a glass base for the espresso which from what ive read is the Chinese version but for all I know that's what I have as well.
Guess what, yours is Chinese also. Not saying thats a bad thing. Its a tough rig.
I have the same base that came with mine still and it may have a few dings and scratches in it from me not treating it so well when I was a noob smoker two years ago. But the threads are still there and they still work.
The best bet is to go somewhere that sells the stargate with glass bases such as http://texashookah.com/modern.html
. Email them or another company and ask if they have any extra glass bases for a stargate laying around and how much they would cost.
