I recommend this Olevia HD media Box. http://www.olevia.com.hk/product_details.php?workplaceID=22&productid=436&langID=E

I have replaced my WD Media box with this one.  The box only cost HK$800 in Hong Kong.  It supports 1080p full HD output, plus new 1080p 24Hz format.  It will pay all format including AVCHD, MKV, WMA PRO, HD RMVB, RMVB, and all others common formats.  You can connect an external Blu-Ray or DVD drive to play like a regular Blu-Ray or DVD player, you can connect the drive to home network wired or wireless (with an USB network adaptor) to play content in home computer.  The box has HDMI, component, and composite output.  
Good price, good feature, and good video quality.
