Thoughts on AUX cables?

[Fatcat]

I've been recently wanting to install the AUX cable on my E53, only problem is that they dont make them anymore and the genuine BMW ones go for $80-$100 I have found some aftermarket ones but not sure if they are good quality or will even fit.

I want to gather peoples opinions on what I should do, any good aux cables that aren't stupidly expensive or should I just stick to my crackly Bluetooth adapter, or is the price really worth it?

I think 4 and 5 use a different type of pin style which wont work on my radio unit (non navigation DSP)
