With a bubble cap from Quartz Pi (pricey but high quality color)
Also recommend a nice simple klein recycler, if you wanted to order one from China, DHgate, or Greek Glass rather in the US, You can get a complete kit with recycler, banger, and cap to get you going...
Also Stache bangers are quite reasonably priced, and check out 710coils for their 710 sale, can get one for at least half of $100, but I don't even like to spend $50 on mine lol
