I think that player was recently added to the mp4nation site. Many people have bought from the site including me. Communication is decent and the players arrive although it can take 2 to 4 weeks from date of order. This is pretty normal from Hong Kong in my experience. Customs clearance in your country can be a significant part of this.
Here's a link to a JXD forum on the mp4nation site that may give you some additional info. Posting questions on it may give you some comfort regarding the player.
