Vaporents

Unfortunately, I'm not knowledgeable enough to know about different qualities of glass, or different sellers. I just know that DHgate is basically a haven for buying bongs. :P

I forgot this isn't reddit and we can actually post links here without being censored, so here's a link to a search simply for "recycler". Looks like they have a ton of awesome stuff, hopefully you can find something you like: https://www.dhgate.com/wholesale/search.do?searchkey=recycler

Here's basically the model I have. I didn't buy it off DHgate, but it's the exact same "torus" design with the percolator at the bottom, and the secondary inner vapor chamber at the top. Only $43, with lots of 5-star reviews, for whatever those are worth: https://www.dhgate.com/product/advance-booking-2015-new-high-quality-glass/218127026.html

Again, I know it's all weird chinese stuff so I totally wouldn't blame someone for wanting to look somewhere else. If you wanted to buy from a trusted vendor, retailer, there's stuff like this:

Matrix Recycler from Vgoodiez, only $50 (Vgoodiez rules by the way): https://vgoodiez.com/products/matrix-recycler-by-vgoodiez

There's probably other sites for that too, but I haven't shopped for enough glass to know all the good places.

Hope this helps.
