Is there an alternative to buying it that I've somehow missed?
Come, let us embrace as brothers.
I always hate saying, "I could afford x,y,z" because it sounds so horrific when you actually say it. But it's true. I simply choose not to buy over-priced stuff that isn't life-enhancing in some way. GPUs are nice but I would hardly call them that. So they get a self-imposed budget restriction based on what I consider to be their importance to me.
Ironically gardening stuff doesn't have the same limitation, because these days I consider gardening (and watching things grow*) to be genuinely life enhancing.
*For two weeks, before I variously over-water, under-water, over-feed, under-feed, neglect or over-fuss them to their inevitable demise.
