There are some caveats with that though (some of which I just found out after some digging):
- You'll probably need more than one flow cell (which is used up during sequencing) for a human genome
- The flow cells make up the bulk of the price, costing ~$800 in single unit quantities
- You have to send in used flow cells for refurbishing (which is how they can make them as cheap)
So the $1000 is more or less already the refurbished price.
