Can any of you recommend an inexpensive TIG welding machine?

I'd like to build a long-john cargo bike out of 2" x 1/16" wall square tubing. I know that such thin wall material can be welded with stick (or gas) but the operator has to be pretty darn good....and my stick (and gas) skills never were terribly good and would take a lot of work to improve enough to get comfortable for this sort of thing; but 40 years ago my TIG skills could easily do it; and they can be quickly resurrected.

But:
I don't need a TIG machine other than this project; used TIG machines aren't growing on trees in my area and they're never inexpensive; I don't want a multi-process unit and don't need pulse or any bells/whistles; carbon steel....that's all I need to do.

So:
Last night I bumped into this: https://yeswelder.com/collections/ti...elder-tig205ds. It's $280 shipped, has hi freq start & foot pedal, and the YouTube videos look promising. I mean....unless it's smoke and mirrors people are making good welds with this thing. My head is spinning.

Have any of you used this machine or others like it in the sub-$500 range? Do they actually, really and truly work well and reliably?

I mean, for context, I'm blown away that a small TV can be built, put in a box, sent to the other side of the world, wind through all the distribution channels and be sold at a profit for next to nothing, so the notion of getting a competent welding machine for this kind of money is difficult to imagine.

Any comments, experience, nuggets of wisdom on this??

TIA
