Rereading this post, I want to clarify that I am not picking on @Reporter at all. The eBay listing just had some comedic elements. We are very happy to have you here and we want to get you a good lathe. I'll stand by the sentiment that buying one from a no-name eBay seller doesn't offer you much confidence in the product quality or their ability to resolve issues. I also would not want a lathe that nobody else has since no one will be familiar with it to help you out.
Grizzly and Precision Matthews would be where I would start looking for a new machine. There are also industrial surplus houses that sell used equipment. That is where I got my lathe. They usually carry larger stuff though.
maybe the biggest problem is the banjo doesn't actually work for many threads and it needs to be modified.
I've had my headstock ripped down and I'm a bit concerned the spindle wall is too thin (3.5mm) but after a **** ton of hours tuning tweaking I have mine working ok, I just hope the spindle doesn't fracture and cause a disaster. I tore down a 7x10 mini lathe which had stress fractures all through the spindle.
