I have one of these NVR with 2 cameras on order now from Costco, cost was $599, not $500. But I talked to their tech support line and liked my experience. I think service after the sale is VERY important before buying one of these kits. Also, found out from Costco (since I've been their for over 8 years now) that this is a NON-Electronic item, so it does not qualify for the 90 day return policy. Which is good, since they said I can return it anytime. That is anytime, ie., next year, 2 years from now, and so on. The only thing costco watches is abuse when customers do this repeatedly. So their is no risk in buying this item to me. IF I dont like it, I return it to the store in my town, no questions asked, and I can take my time setting it up and testing, which is big for me!!
