I still prefer the RED One (with MX upgrade and SSD, etc) to the Epic/Scarlet simply because the MX doesn't have a fan that blows like a hairdryer at the talent and at me (granted, usually just in between takes, but that's still annoying). I like the added heft of the MX, I like the XLRs and other i/o that's just THERE all the time. And we kept ours because it'll still be a usable camera for another 2-3 years, as we replace RED parts with other vendors' parts.
But as a rental item? It depends on your market. In LA? No way.
And it's not the camera we use most often for smaller things like corporate projects. Mainly, I'm using the RED on greenscreen type shoots.
