OEM (or best aftermarket / 3rd party) replacement back / battery cover for Lumia 640?

[Synomenon]

What's the consensus on the best replacement back / battery cover for the Lumia 640? It can be OEM or an aftermarket or 3rd party brand. I'd like a white one, but not sure what to buy. I see alot of sellers on eBay and Amazon.
