Given how much time these models can save me, I'd rather optimize for capability and just accept whatever the price is as a cost of doing business. (Within reason I guess—I probably wouldn't go beyond $2-3k per month at this point, unless there was very clear ROI on that spend.)
Also, it's not only about saving time. More powerful AI tools allow me to build things it would otherwise be impossible to build... that's just as important as the time/cost equation.
