FİYATLAR ( Bilgilendirme amaçlı yurtdışı fiyatlarıdır)
Relook 400s >> HDD siz yurtdışı fiyatlar: 400$
120 GB HDD : 629 $
250 GB HDD : 680 $
Dreambox 500s >> Yurtdışı fiyatı 350 $
Yorum: Dreambox da CI ünitesi ve HDD yok.Card reader ı var.Twin tuner yok.
Relook 8 MB flash bellek ve 96 MB SD-Ram e sahip. Twin tuner ve isteğe göre arttırılabilen HDD seçeneği mevcut.
Her ikiside HD teknolojisine sahip değil. Sharing yapabilen, LİNUX işletim sistemli cihazlar.
HD yaygınlaşana kadar kullanılabilecek fiyatları orta ve üzeri ancak kalitesi yüksek cihazlar blush
