The Home Assistant-branded ZBT-1 [0] is $30ish and, if your goal is Home Assistant, you're probably better off going that route especially now that IKEA is going all in on Thread/Matter (which the ZBT-1 supports in addition to Zigbee.)
I do have that particular Sonoff dongle - as well as a ZBT-1 - and I can vouch that the dongle works as well as the Hue hub it replaced, controlling a couple dozen lights.
