Gawd I don't want to even figure how much money I've invested in my board. Eesh. But, to me, it was worth every penny. And I'd rather spend the little extra money on good, reliable patches. And as stated, it all depends on what your definition of expensive is. I don't think George L's are that expensive. Especially for what you're getting.
RG 58 A/U, 100 ft roll = $17
George L .155 cable, 100 ft roll = $195
That's my definition of expensive. And for no discernible benefit, I can't justify it.
I do like their solderless right angle plugs though, but again:
GLS Audio pancake head = $1.50/each
George L right-angle solderless = $7.75/each
There's nothing better or more reliable about George L cables, so the slight benefit (smaller size, and solderless construction) isn't worth the cost in my book. But everyone's book is different.
