Duty cycle is really important if you're going to be doing decent sized jobs. The cheapest welders usually have a very low, almost unusable duty cycle.
If you're going to be doing mostly 1 type of welding, a dedicated 1 purpose machine is going to usually be better than an "all in 1" type of machine.
A machine like a Miller or Lincoln while they cost more, often perform better but more importantly can be serviced/repaired. And getting parts is usually pretty easy.
Amazon/HF/cheap chinese welders are pretty much throwaways if they break and/or have problems.
The first AC/DC TIG machine i ever owned was an Eastwood. Not water cooled but it was a decent machine. The foot pedal was crap but they offer better foot pedals now. It was pretty cheap but also decent quality.
I would recommend staying away from the absolute bottom of the barrel cheap welders. They usually suck.
Another thing is features- many welders offer tons of features but if you'll never use them, why pay for them?
Will you need the welder to be portable? Will you be welding outside? How thick of material will you be using? Will you be welding strictly steel, or will you be welding aluminum or stainless as well?
All of these are important considerations, quality and prices vary wildly so proper research is paramount.
