Yes, the yet-to-go-into-full-production E7 was spotted on DealExtreme.com for a little over $81. While DX has been selling FiiO's products for a while now, I am not fully sure how they manage to secure enough E7 for sale. Last I checked, FiiO is still waiting for parts and the estimated time for full production run is mid April. The pre-production batch (including the one I have reviewed) are meant for review purposes. Maybe FiiO is selling the left-over (so to speak) to DX? I will check with FiiO tomorrow and hopefully we can clear out any doubt.
[UPDATE] Got words from FiiO. The E7 that DX is selling are indeed part of the pre-production sample batch. Somehow DX is able to get their hand on a very limited number of them that are supposed to be sample for the sale agents (or maybe it is the sale agents that give their sample to DX for sale?). In any case, those are not the final production run so buy it at your own risk.
