Well the seller is assuming all responsibility for the listing and for a 16GB set, $300 is most probably legit... Go for it with paypal and you can always dispute if IMEI isn't found via Nokia Suite so even with a 5-star rating you'll have the upper hand although the seller seems pretty legit... I would like to know about your E6-clone if possible as I didn't know it was that easy to port Belle into another piece of HW... Also did you try that E6 on Phoenix? That would solve if it was really a fake or simply the Nokia system you queried not being able to find the IMEI...
