About the lock actuator.

I'm confused, I'm looking on eBay and Amazon, and I'm confused, I'm looking on eBay and Amazon but there is much difference between the price of eBay and Amazon, about 60 dollars. I wonder what's right, I have an Acura TL Base 05.
Is this part 72155-SDA-A01 or this 72655-SEA-G01?
