ownta and Jtshop seem to be about the best places for these devices, I just happened to be browsing the ownta site, saw this and hit the buy button, you now how it is.
Later I found JTshop have it a bit cheaper! Also noticed JTshop are starting to get a lot of new stock in now, like an onda with a metal front bezel, I wish i'd waited now!
Here are some more photos.

Has the usual set of sockets
Again this player is lacking volume buttons, in fact it only has one
button which doubles as an on/off and back button.
The cheaper smart PMP do have volume buttons which for some apps works
much better in my opinion.
Come with it's own display stand
If your Android doesn't have a stand like the Window pro2 then these plate display stands are a good idea cheap from ebay
Out of the 2 players I have reviewed I would say the WindowN5 pro2 is much the better player
for very little extra money, the build quality on the Window N5 MID is better and so is the
firmware.
There is quite an annoying issue (at least for me!) that if you plug the Onda device into a wall charger it always boots up, the Window N5 doesn't do this so you can charge it while shut down.
I have ordered a carrying case for the Onda which I will review when I get it.
