Just some thoughts that may or may not be helpful?
As a beginner I went for the Axminster C2. Reasons?
It's not a fly-by-night company, and has a shop within 50 miles of me (although I had mine delivered). The size, heft, and extra weight of the box it came in made it a two man lift until I unboxed it.
As I said, I'm a beginner so I didn't worry about the finer details, I just wanted to start cutting metal without a great deal of fuss, so I jumped in and any issues I'll correct as I go. First thing I did was order two cans of the correct paint colour for the cream/blue scheme to touch in the rough areas. It maters not a jot to the function.
Support from Axminster has been excellent, and the whole process of ordering, delivery and subsequent comms with the company very smooth.
I intend using it exclusively for several years until I come to the point when I will buy into the next size up and my C2 will be either relegated to a second machine, perhaps being set up for specific tasks, or sold on (they tend to hold their value quite well, and prices surely will only steadily increase on new machines),
Mine only has a 250w motor, but as a beginner I doubt I'll notice that as I'll not be taxing it that hard. I don't think I will get the benefit of a brushless 500w for what I do with it. With some TLC and a bit of time and effort they go from cosmetically basic, to quite nice (in my eyes).
There is a vast amount of modifications that can be made too, if tinkering is your thing.
From what I've read and seen, superb work was done in the past by owners of far inferior lathes, so I would just pick one of the established companies, and just enjoy whatever you buy.
