This - storing implements that you don't use is expensive (if you keep them covered) and takes up a lot of space. Get what you need for the task at hand (I'd take the approved CFO money and put it in a bucket for those projects for when they're needed.) Things like a PHD, if you need it for one task really, rent it from CL... i.e. buy a used one, use it, and sell it for about what you paid (or more if you get a good deal).
