Whenever I see monster stuff at princess auto in the surplus section I pause and sometimes pick up spares.
I buy blue jeans interconnects because I can get custom lengths made up and its a "never wonder if" purchase. A fair price for a no BS product I think. You could spend more for sure, but I consider their offerings the most I'd ever pay. I always get my stuff inside a week with them. We pull a lot of Belden on high spec jobs, so I like Belden is their no nonsense go-to.
There is heavy markup on cables, especially once marketing spin starts, so keep that in mind.
