Starting setup, X1700H vs X2800H (or DRA-800H?)

... Except that now I am seeing 2800H for eur 720 and 1800H for eur 790. How about that.

That does not makes sense but it happens. Sometimes only specific models are on sales and makes them cheaper than lower end models.
It could also be that some retailers are selling 1800 more expensive than they should
