Aftermarket fuel tank breather options?

[Rod.bearings]

Before I buy OEM, wanted to see if there were more cost effective options? Part number is 13907831770. I do see some on eBay but unsure of the quality

I dug around m5 board and they were able to find a aftermarket version that was a OE rebrand.

I just replaced this valve with genuine BMW since it was only twice the cost of the others. The genuine final stage resistor is like 4x the cost of other brands...
