Inverter Welder: Itamati 200 EI vs Ripper 315a - Which DIY Welder to Choose & Opinions?

Hello. I'm going to buy a DIY inverter welder and I liked the two models but it's hard to find any opinion about them. Maybe someone from the forum had the opportunity to meet and test one of the models? It seems to me personally that Ripper is better but Itamati captivated me with something and I am constantly trying to see the advantages in it. There are a few videos of Itamati welding demonstrations on the internet but they are suspiciously short and these are only momentary welds and I would like to know how the welder behaves during "standard work" which will take a little longer. I am interested in Itamati 200 EI welding machines and Ripper 315a.

Thank you in advance and best regards.

Maybe I will not recommend a specific model, because with such cheap toys it is different, although it is worth getting interested in the Arc force function, I did the welding test with this option (percentage adjustment with a separate potentiometer) and you can practically push the electrode into the material.

And for example this one here?
