Looking at this one from wen..
That looks like the one I mentioned above, which is what I've been using since 2020. Its a pretty solid lathe. It's turned more than my big PowerMatic thus far, by a long shot (although, I didn't get the chance to manufacture all the bowls and platters I had planned to last year, hopefully in 2024 this will change.) Anyway, the Wen has helped me craft hundreds of pens, at this point a few dozen christmas ornaments and other christmas decorations, and a few vases and a number of small bowls.
If you do get the Wen, which IMO is a darn good value for the money, there are going to be a couple of things you'll want to do. The most important of which is to properly align the headstock. I actually just did a little bit more aligning of mine today, as I received a replacement mandrel for my Beall buffing system. The mandrel is over a foot long, and it helped me identify the fact that the headstock, despite a past attempt to align it, was still not pointing properly. I loosened the four allen screws that hold it in place just a bit, so it was till fairly tight but could be moved with some soft tunks on the headstock or chuck with a mallet, and aligned down to about 5-7 thousandths. I can't seem to get it better than that, and I suspect some of the discrepancy might actually be in the metal of the mandrel itself, not actual mispointing. So the headstock is now pointed pretty darn near perfect.
I had tried this before, but only had a much shorter distance to align over, and it clearly did not align well enough. I would say, this one tuneup in particular, will help deliver optimal turning results, especially for pens. The other tuneup I would do, is to pull the tailstock off, and adjust the nut below the locking plate so that you can sufficiently lock down the tailstock. Mine was not tight enough when I first received it, and needed some adjustment to get it to the point where I could actually lock the tailstock down. If the one you have listed is the 34035, then it has some improvements over my 34034 that resulted in tailstock slippage, which I've never been able to fully correct. I think the 34035 is issue free there, though.
Anyway, with these two key tuneups (which IME are generally required with any lathe, but its a little harder to do with the wen since the headstock is bolted in place and not movable) will help dial in the performance of the lathe and reduce things that might give you out of round or non-concentric turnings (which really only matter with pens.)
