My opinion, buy one time correctly.
Can’t use the amps you didn’t buy.
Stick with a quality brand like Lincoln, Miller or ESAB.
I personally bleed Blue, so I am Miller all the way. Lincoln did make the best transformer stick welders back in the day, I’ll give them that. I’ve never welded stick with anything better than an old Idealarc Roundtop.
I’d recommend finding a used Millermatic 200 and not looking back. They rated it at 60% duty cycle, and it’s the same welder as the 250 with less stuff to break. It’s a big pro machine and arguably the best MIG Miller ever made.
If you want to dabble in tig, get a bottle of argon and a torch setup and you can scratch start off of your Stick welder.
