seems the brand too new or too shitty …

What does affordable mean to you?

There is this instrument from PCE, but you will need the adapter to go over 10A.

They also sell hand-held clamp meters that are half the price, but not desktop style.

If you want to put something in your own case, you can by a power meter and then the appropriate current transformer.

Alternatively, you could utilise a power transducer and link it to a laptop / computer for the display. Again, this would be more of a self build.
