Power meter vs better trainer

Do you want to be able to use ERG mode as well?
If so, Elite Direto, Tacx Flux or Wahoos Kickr Core might be what you’re looking at. Also Elite Suito received great reviews, I think even from DCRainmaker. Maybe you can find one of them used.

If not, you might want to look at sth. like the Elite Kura. It has a PM installed and is super reliable, and besides doesn’t require power supply for that.
The only drawback is that ERG is missing, so you’ll have to shift gears or change cadence to adapt required power output. But that can also be a great thing, especially for very short intervals.

Best Dumb Trainers

For me, I feel that training according to power is great. At the same time riding outside according to RPE is also great, so I’m not really missing a powermeter outside.
