Siglent seems to be the benchmark for LOW QUALITY. I have not owned any Siglent instrument, is it really that BAD?
No it isn't. The hardware is quite decent and the rust is a running gag but the biggest let down in Siglent equipment is the buggy/incomplete firmware. When it comes to built quality I'm not impressed with the RTB2000 and that is mostly due to the surface mounted input BNCs which aren't bolted to the chassis and the way the PCB is mounted. You won't find that kind of cost optimisations in GW Instek, Rigol or Siglent scopes. In those the input BNCs are bolted to the chassis (for as far as I have seen so far) as they should because these connectors get a lot of abuse.
edit: Made in China means they can built things properly while still keeping labour costs down. Even in the Czech Republic it will be expensive to have an employee mount a PCB onto a metal frame and tighten a couple of nuts on 5 BNC connectors.
I watched Mike's breakdown and it looks like the jacks are pretty well built on the RTB. I've run high end instruments for years with stuff on PCB boards and even designed circuits using the same technology. I don't know of many laptops that don't have jacks attached right to the board. Done right they're not really a problem.
Saves a ton of time and production costs just like SMD over thru hole does. It's the future, the less labor and the more automation the cheaper it is, heck I'm doing mostly SMD now. The world is working to eliminate jobs, it used to be that we spiraled down to the world's cheapest labor force but those days are coming to an end.
Get an education and run the robots or hope you get one of the few manual labor jobs left. I got an education, I figured it was better than hanging off the back of a garbage truck at 6 am, I have an aversion to bad odors!
