Hello Jeffrey - Happy Holidays! I received your DM regarding Helium Monochrome brains. I just sold 2 and have more. The brains I have now have 4 hours and 10 hours on them respectively. Brand new essentially. Come with Jet Packs (SDI), power supplies and sidekicks. I have the flight cases as well. Pics asap. I'm asking 5K USD per brain. You can reach out to me at mike@subterrafilms.com or call 646 295 7590. Thanks! Mike
