Take DC2N, change it so that it can take firmware updates from the SD/SDHC card and you’ve got DC2N SE (which is NOT DC2N2 – we’ll have to wait for a while for that).
I am finishing the testing of a DC2N SE I’ve put together spending quite some time so if you think you’d like one, find below the details.
Price: £110 including shipping via standard mail (if you prefer shipment with a courier I will charge accordingly; if you pay via PayPal, then you have to pay for its fees).
Yes, it’s a lot of money, as I spent a lot of time in building it. I’d recommend you to spend your money wisely based on your own needs. If you can afford to wait for quite some time, DC2N3 and 4 might be a more affordable proposition (maybe not so much the prototypes but the finished unit should be way more affordable).
I will slowly work at a few more DC2N SEs in my little spare time. Keep your eyes open if you missed one.
