I'm not a trained machinist, though I did operate mills and lathes as about 10% of my duties in a couple places I worked over a 25 year span. Plus one quarter of Machine Shop at community college. Just so you know how much weight to put on my opinion — not much! But I have the exact same mill (branded as Enco) and I really like it. I previously used knee-mills including a Bridgeport, so I'm very aware of the limitations and annoyances of one of these, but given my space and budget constraints, I don't think I could have done much better.
Grab it quick, because stories of losing a machine from being too slow are pretty common around here.
I stongly advise you to take it apart before using it at all. Clean everything, inspect, replace bearings if necessary (probably won't be), regrease, oil the ways, adjust the gibs, and when you're done it might even be better than new. Lots of these were bought by hobbyists and got low "miles". But the teardown/rebuild will not only make it work better and last longer, but more importantly it'll teach you about it, better than any user manual or youtube. I had to take mine apart to carry it downstairs to the basement where it lives, but I'm glad I did especially for the knowledge. OK I'll admit there's something to be said for "just use it", if mill-rebuilding isn't your idea of fun. Don't let worrying about a rebuild keep you from buying it. Just, as a bare minimum, lube everywhere before using it at all.
Speaking of youtube, I've lost track of how many videos there are about this specific mill, probably dozens. Search for "Mill-Drill" and "round column mill" as well as Rong-Fu. Start with a couple that walk you through the whole teardown-rebuild. Let me know if you can't find them, I have some saved in my "Watch Later".
Hope you have a lot of fun with it.
