Hi everyone, longtime lurker, first time poster.
I just got off the phone with a guy at Centronics Customer Service. He couldn't have been nicer in accepting a pre-order for the ZAT502 HD.
Since this is my first post, I can't post clickable URLs. copy and paste this: centronics.com/product.php?id=48
(lowest price I could find, also, they'll have it first)
He pretty much admitted to me that they were caught with their pants down on this item during the DTV transition. He was laughing about how last year, they could barely give these boxes away! Now, it's a hot item. He also said that he owns one of these boxes personally, and it's good for him. I told him that I heard about it here on the AVS forums, and he said to say thanks to everyone for talking this box up.
We ended the conversation with the info that the box *SHOULD* be in and ready to ship within the next 2 weeks, hopefully and possibly sooner. He said that he just got confirmation from the manufacturing plant that all the units were ready, and were just waiting on boxing/packaging, so definitely soon.
