Which is to say, I understand that I understand nothing about financial systems. Oh, there's this part of a financial system that involves actual mathematical rules, and I'm not terrible with those bits -- adding, subtracting, etc. -- it's the parts that have to do with all sorts of bizarre regulations and sequences and fiscal years and quarters and AAAAARRRGH. Brain shut down.
So my assumption, since purchases for new hardware are automatically (in my mind) Too Expensive, was that getting a new hard drive was Out Of The Question. This is apparently not the case.
Shopping will ensue over time, and I expect that, in an attempt to remember what I've done and what I want to do, notes will follow here.
First up are some friends who may have barely-used hardware floating around, and then some discount places. If I absolutely have to, I may well end up at Best Buy. (I did purchase the machine from them, which, if my spotty memory serves, may mean they'll install it for free and warranty the work. I'm only guessing here, though.)
