I'm designing a system including a 3 V coin battery.

I am looking at a catalog of coin cell battery holders / sockets.

Their cost varies from 0.25 to 2+ euros (single item), so we can say there's an order of magnitude in difference (it's quite a lot!).

From the datasheets they all seem mechanically robust enough for your typical pcb application, irrespective of the price.

They also have basically the same footprint. 

So why choose a more expensive one over the cheapest one?
