Is this cheapest-of-the-cheap kit okayish for the money, or is it just throwing money away?

The product is not bad. I built one like that a while ago. Just make sure they supply a power transformer to suit your mains supply voltage (220v ?)

However, you need to be able to read and understand a schematic diagram, and identify components visually, as the only assembly instruction is a schematic on a piece of paper.
For a first timer with no experience, you will need someone knowledgable to help.

Put together right, it actually sounds not bad, and the output transformers are good enough to be the basis for something better.

You should be able to get 2-3W out of that. The power transformer will likely self destruct if your line voltage is much over 220V.

All right, having read up on the dangers involved in HV tube amp kits like these I think it's wise to leave this be for now.

I mean, I've assembled some speakers and repaired some stuff before, but none of that was as really dangerous.
What worries me is that a site like Banggood sells this kit like it's a model car kit, for any inexperienced person like me to try.. without warning that any single mistake during building this can cost me my life.

In all fairness, most tube amps would be similar in risks. Dynaco sold huge numbers
of tube amps and preamps, apparently with few such problems. But, some people are
more careful then others. A good assembly manual, apparently lacking in this case, is
essential for beginners. Look at this one as an example of a reasonably good manual.

So what would be a good "budget" / starter kit for someone like me who's got soldering and assembly skills, but lacks in depth electronic skills?

Depending on your budget, I would recommend anything by tubelab. You will have to gather some parts yourself but you will have a full community around to help you through every step of the process.
