Simple home tests for indication sleep apnea?

I've seen a few FDA approved devices for a home sleep apnea test for a little less than $200 but I'm not sure how accurate they are for detecting sleep apnea. I think they only measure breathing. Here's some information that might be helpful if you are shopping for one of these tests.

I recommend getting a nocturnal pulse oximetry test ordered by your Dr. You just wear a pulse ox sensor on your finger all night, it’s recorded overnight and if you have significant drops in oxygen levels you may have sleep apnea and get can get a sleep study done. If oxygen levels stay up in normal range sleep apnea is highly unlikely. This is so much simpler, done at home, way less expensive and a good screening test. If you sleep with someone else, they can tell you if snoring, gasping and stopping breathing are happening. Their input is invaluable.
