Bike Tires Direct has factory refurbed Garmin Edge 820s with 1 year Garmin warranties on sale for $150 today, 8/13/22.
I bought one a month ago for $190, and I'm happy with it. It's not perfect, and it uses more juice (about 1mile) than my old Lezyne, but it does more than my old basic Lezyne. Great display, great function. True, the touchscreen function sometimes misses, but pressing buttons don't always work as intended, either. Great price.
