There's CNET reviews and this list from Amazon for unlocked phones.

I'd skip the sub 99 buck models. What looks good to you?
For reasons not worth getting into my regular everyday phone is an iPhone 5...yeah small screen. For work reasons I'm sort of stuck with it for now.
But for the times I'd like to watch a movie I'd like to get another phone so I can just slip my sim card in and watch my netflix on a decent sized screen. This second phone I'm wanting to purchase would only be used for the short times I want to watch movies, so any other feature the phone might have is not so important. Just btw I'm on AT&T with unlimited data.
So considering I'm wanting the largest screen size for a reasonable price, what would be a decent quality but cheap used phone/device I could get to watch movies on?
