Have you looked at Lofta?

https://lofta.com/products/sleep-apnea-test

Disclaimer: I've not used them. No experience with them. I've just seen their name mentioned as an affordable sleep test.

EDIT: Just realized the company of this submission has similarly priced sleep apnea test. I should have probably clicked through before commenting.

Lofta does sell CPAP machines whereas Helio doesn't. I just did my sleep test and follow up through them and the process was quick and painless.
