nicely put comparison, just a simple lowest available price clarification:
$499/Amazon (@ Newegg even less, depends on luck)
$850 is the maximum price I`ve seen (don`t think the guy actually sold one)
$698/Amazon (but you need to wait a MONTH in order to get this price)
$899-$1599 at other retailers
so you were not really comparing models from within the same price range, at all...
I`d say you could easily compare it with Class D Elite SC-55...
