A little late but WELCOME! ESB builder here. As others have said, Arkady is the one to go to for the flight suit and vest. Great service and quality. She can't be beat. My best suggestion would be to do COPIOUS amounts of research on what you need and who sells. Look for seller reviews as well so you don't get screwed or get bad services. And feel free to message us if you have questions. You can always PM me if you want. I'm in the process of my build and have most items procured. It's definitely a journey, but a fun one! Happy hunting!
