If the S70 were a long-established remote that had a very stable history, I could understand going the cheapest route and taking the risk of no warranty coverage. Maybe. If you're really strapped for cash. But I personally would be reluctant to buy a product as new as the S70 and risk a possible total loss if it's defective.

Anybody could call a sale "legitimate." When you think about it, that doesn't really mean anything. On the other hand, if he can prove that he is an authorized Nevo dealer or if you can verify this by contacting Nevo, the remote should have full warranty coverage. Like everything else, you often get what you pay for. Support when you need it on these remotes has very real value, and I believe it's worth paying for, even if that means bypassing the lowest-cost source.
