media player?

Looking forward to complete my home theater system (for beginner that is). So for the final piece i'm looking for HD media player. Been torrenting a lot of movies. I need it to be:

• support HDMI - need to support full HD 1080 or 720
• support MKV & Mpeg-4 files
• black in color
• medium range

A few device i found& I'm intrested in 

KWorld Media Player M200

Seagate FreeAgent Theater + HD Media Player

Hurm, going to PC expo tomorrow with Prabu & Amin. See what i can find. :)
