Jburkart,
I would advise you to ask the dealer to give you his complete margin on the upgrade. He clearly misinformed you. Perhaps the wrong upgrade price he gave you when you bought it is not his fault, but it certainly is not yours.
Making profit on new boxes is one thing, but making 35% on a upgrade seems too high to me, and reading your response is scaring you away from the brand. Not a wise dealer in my oppinion.

Also watch out that he does not try to sell you a new front. This is not adding any functionality.
I bought a 2nd hand 800v2, and got the upgrade for much less than 5600 Euro's. So it is possible to get some discount.

I like the DVD-A playback very much. Also the DVD-V playback in 24/96 is great.
