I was thinking exactly the same when i saw that DINOelaine posting links towards DINODIRECT.
Anyway, i bought mine from their shop (I bought it 1 day before DX got it) and there was nothing wrong.
The delivery time is quite long (expect more than 3 weeks) but i got a tracking number even if i choose the cheaper cost for delivery (it's seems to be mandatory to France). I payed something like 63 ? (using coupons) but i also got some little gadgets with my JXD.
I'm really happy with my purchase. The JXD run with an OC kernel (stable at 850 Mhz) and is really great for PSX, Nec Pc engine with CD sound...
I'm currently working on a nice windows phone 7 theme wich looks great !
To come back to the subject, the price for the JXD is quite good, i tried to use some coupons and i found that you can save 2,90? by using TOPSAVE.
It's 52,08 ? for the JXD wich is quite good i think if you don't mind waiting for really long time.
