Well I had UPS date of 1 day shipping since I am close to their factory. Of course it didn't happen. Took 3 days. Messed up part UPS kept showing it was out for delivery and then change it to delay (no further info).
In any case, about FM's shipping. I agree that they should change estimated shipping times as they change. Being a small company, I get they don't control their supply chain so things change from what they were told would happen. However, I think they should update everyone.
That being said, it does look like they have moved back to the 6-8 week delivery based on what others have said and my contact with them.
