How to sequence your DNA for <$2k

Hi, believe it or not, I have actually done what the authors were attempting. I used saliva rather than blood as a source of DNA and extracted it using a Qiagen kit.
My Nanopore flow cell had nearly every pore working from the start. So I would say that is not normal. Maybe it was stored incorrectly.
I wanted to try this, but I looked into Nebula a bit more.
Nebula is facing a class action for apparently disclosing detailed genomic data to Meta, Microsoft & Google. The subreddit is also full of reports of people who never received their results years after sending their kits back. There are also concerns about the quality of sequencing and false positives in all DTC genomics testing. Given what happened with 23andme as well and all of this stuff, I'm wary of sending my genetic data to any private company.
It's frustrating but anyone who has your DNA would be able to fairly easily deanonymize you to a degree [1] even if your submission and payment are anon due to the nature of DNA.
I'd happily pay a premium for a service that would show the controls they have in place to assure data/sample destruction etc.

Even when the raw results are accurate there is a cottage industry of consultants and snake-oil sellers pushing bad science based on genetic testing results.
Outside of a few rare mutations, most people find their genetic testing results underwhelming or hard to interpret. Many of the SNPs come with mild correlations like “1.3X more likely to get this rare condition” which is extremely alarming to people who don’t understand that 1.3 times a very small number is still a very small number.
The worst are the consultants and websites that take your files and claim to interpret everything about your life or illness based on a couple SNPs. Usually it’s the famous MTHFR variants, most of which have no actual impact on your life because they’re so common. Yet there are numerous Facebook groups and subreddits telling you to spend $100 on some automated website or consultant who will tell you that your MTHFR and COMT SNPs explain everything about you and your ills, along with which supplements you need to take (through their personal branded supplement web shop or affiliate links, of course).
Yeah but then basically somebody else gets ownership of your genetic data and gets the right to do anything with it in the context of their "legitimate interests". Not to mention to probability of that company getting hacked or sold, as it has already happened with some.
Speaking of which I would advise : Svante Pääbo Neanderthal Man: In Search of Lost Genomes then even better imho The Naked Neanderthal by Ludovic Slimak. After these books I spent many hours listening to the full courses of Jean-Jacques Hublin, chaire Paléoanthropologie in college de France ( in french but probably translatable now with automatic features ?). This was an unexpected and wonderful path.
Interesting concept, but between the broken hardware and the way they gave up before getting anything useful this article was rather disappointing:
> Another problem was our flow cell was malfunctioning from the start — only 623 out of 2048 pores were working.
Is this normal for the machine? Is there a better write up somewhere where they didn’t give up immediately after one attempt?
