Tarptent AEON Li one person tent. I bought this tent for a planned JMT trip last year but I only ended up using it 2 nights. On my scale it weighs 1 lb 3.4 oz with the stuff sack and 6 stakes. New it goes for $569 + shipping.  It’s in great condition. A treking pole (not included) that extends to 115cm is required for setup. The setup is fairly easy but you should watch the setup video at Tarptent.com because it’s not intuitive.
