Initial investment cost to build reactors would in all likelihood be very high just by the nature of these being some of the most complex machines on the planet. It seems unlikely any sort of fast manufacturing line could be created to build these, and they’d all likely be built one at a time like fission reactors.
Running costs and maintenance would also be high, the fuel alone is expensive (right now), and I’ve heard that wear and tear on parts of the reactors can be high so much of the housing for the reactor would need to be replaced with time.
You’ve probably also got a small army of engineers running each one of these reactors you’ve got to pay.
All that said, the energy produced via fusion is EXTREMELY abundant. I imagine with later reactor iterations (after supply chains have been setup and electrical transportation routes upgrades) electricity could become very cheap even relative to renewables.
