Refurbished ones are just as good as fresh ones, and basically always “on sale” since their price is reduced.

Valve seems to be moving towards a very likely Steam Deck Refresh. Very little is known about when or how this will happen. Based on previous comments and data-mining, the refresh will have the exact same amount of gaming-power. It may, however, have a better WiFi-chip, better screen, and stuff like that. Nothing is certain and if you want a Deck soon-ish, I wouldn’t recommend waiting for this.
Cities which had someone blow a horn to wake everyone up would also have watchmen walking the city at night. Presumably, they would wake the next person up when their shift ended so that someone is awake at all times.
