It really depends on your lifestyle. Most machines will need some heat up time and if you're not sure you won't be pulling another shot for the rest of the day, it'll sit there, consuming like 1000+ watt of power, at least when the heater is on.
I got myself VBM Domobar (HX) more than a decade ago, and still going strong. I don't regret it. It was especially useful during covid lockdown.
Again, it really depends on your lifestyle. It is higher maintenance than any filter brewer. Demands higher end grinder, although those are much more affordable these days.
I just use the cheapest fruit dehydrator and snips away some of the trays.
