I have an order I put in at OpticsPlanet, Nov. 2nd, 2021. Expected ETA in the beginning was just a few weeks. Then it was moved up to June 2022, now "Unknown ETA, please contact us for more details". Just cancelled that order.
I have one other order for a QD mount, and its expected shipment date was originally in 2023, but was moved to April 28th recently, but today it's been bumped up to May 1st. If that date gets pushed forward again I may look for another source.
It would help if they were a little more transparent on their stocking and shipping problems.
