I don't have too much to offer for sage advice. I just bought a Flsun qq for my first 3D printer. I am maybe 10 prints in, and having a good time. I have some issues that I am trying to work out. When I print https://www.thingiverse.com/thing:2656594 (all in one 3d printer test) my prints don't come out as beautiful as others out there. I will learn.
But what I will tell you is it is a beautiful piece of art that any geek would be proud to put on a endtable and showcase in their living room. I am really happy with the fit and finish. The touchscreen works great. It is quiet as a mouse. I spent a long time watching youtube and watching people review every printer on the planet and I had never heard of the qq before I saw it on ebay. I like being a little different and it wasn't enough to just go Delta, I went qq..
