AFAIK the cost of consumables are amortized by doing a few people’s DNA sequencing in quick succession. Low cost suppliers like Dante Labs will run specials where you agree to wait longer and they’ll fit you in with a batch with other people who will pay extra for faster results. Oxford Nano-pore will sell a kit that I think is $1K but the training on how to use it is a lot more. Hopefully technology will keep getting better.
