How many weight plates do you have your gym stocked with ?

Right now , I have 315 lbs of assorted weights

I was debating on picking up some extra 45lbs to avoid me having to rely on the same plates for every machine . But was also thinking the money may be better spent on getting another machine as I have a huge space for my home gym.

So I’m curious, do you have just enough? Or do you have enough where you can keep some on some of your plate loaded machines and avoid having to rely on the same plates for all excercisss
