I think that will be difficult the next week(s).
There were only a limited numbers available, and they are completely sold out yet. You cannot even pre-order them anymore at
www.mediamarkt.de.
Maybe there are some at eBay but only for horrible prices. The Xoro HSD 400 uses also the ESS chipset, but i heard nothing good about it. (And its also sold out)
I cannot really recommend them until know, theres no zooming for AVI files, (only typical MPEG resolutions are zoomed to fullscreen), and no support for 2 Audio streams.
The zooming should be fixed this month but lets wait and see...
