Agreed. The bottom line is that Pioneer just doesn't want Elite/Premier sold online.
If you call in an order to 6ave, it is kosher (according to her) as they are authorized to sell Premier "face to face," just not online hence why the format of the receipt has some bearing. Again, take it for what it's worth - there is no guarantee. But hey, maybe Obama will add Pioneer Premier warranties to the stimulus package so everyone is treated equally... haha!
Trust me, I understand the concern regarding the warranty as one of my 980BT's is in for service right now and one of my previous Premier units (860) was in for service twice. I inquired regarding the warranty as my F90 came from an authorized dealer and I'm possibly going to buy yet another, but regardless of price it absolutely must have a valid warranty.
