It looks like Nebula Genomics has a 12-hour sale (as of this posting). This means you can get medical-grade 30x sequencing for $299. I do not recommend 100x because that gives you little bang-for-the-buck.
Nebula has had issues with timeliness in the past, so don’t purchase it expecting a rapid turnaround. But this seems like a good opportunity to get whole genome sequencing.
The main reason to do this download the raw data and put it in a lockbox somewhere. You have it for the rest of your life then.
