Stickman??

There are numerous guys on AGN using Stickman and it is QUALITY . The big gauge is dead on accurate and the hose is top notch . I have seen a number of cheap hoses bulge and that is scary. This is something you don't want to cut corners on. I use it and guys are always commenting on how much better it is then most others. They are great guys to call and spend the time required to answer your questions. https://airtanksplus.com/product/stikman-scba-pcp-fill-system/
 
I have one, and I am very happy with it. Top quality materials. My favorite feature is the male foster fitting with a check valve. I hook my Yong Heng compressor to that fitting, put a plug in the end of the fill hose, and then open the main tank valve. This lets the air begin flowing into the SCBA tank as soon as the compressor builds up enough pressure. I tried one of the cheap Chinese fill stations on Ebay, and it only lasted two uses. Yeah, it's a lot of money for something so small, but they tried very hard to make it well worth it, and I think it is.
