Before I purchase an Rtech one, anything on the used market?

I bought a Rohr tig last year as I got a deal on a factory return. I was comparing the Rohr with the Rtec ones and it was price that swung it to Rohr.
I don't think the Rtech is a budget unit, they look like good welders. Not having used one and only going by specs and YouTube reviews.
Good 2nd hand tigs are not easy to find at sensible prices. Hope something turns up for you.

I had a budget tig for many years, I was starting to think I was never going to be able to do decent welds. Then I bought an rtech, turns out I’m quite good
They are brilliant welders and the company are fantastic to deal with, I can’t recommend enough.
