The 7 TPI had also caught my eye and wondered if that would be a problem. I think the lathe is mostly if not all metric. Don't know if that would make it unsuitable for imperial threads, or cause problems with the dials.
I have some other concerns as well, such as the bed length and the short 1" travel for the compound. Don't know if those would be too restrictive as an all purpose lathe.
I would see if the manual is downloadable and see if a change gear set is available. You can then calculate the available thread pitches using that 7tpi screw to be sure it meets your needs; if not, then that's a deal breaker. I've seen reference to a 7tpi lead screw on other Chinese lathes but it is unusual.
All the travel limits on this lathe are short, not just the compound. With only 1" of compound travel, if you ever have to cut a Morse taper on your lathe you won't be able to do it because a taper attachment probably isn't available. With a 1" spindle bore and only 18" between centers, you are limited to fairly small or short work. Depending on the kind of stuff you do, this may or may not be a problem.
They do not list the spindle/chuck mounting pattern. If it is the typical 3 bolt attachment thing then that limits your choice of chucks to some extent. Many asian lathes mount chucks this way but if you want a high quality chuck then you may be looking at backplate mounts.
The motor is only 3/4HP, not a real powerhouse. Max speed is 1626 rpm - okay for most steels and smaller work. For aluminum, its on the slow side.
Overall, judging from the specs and capacities, I would say this is a very light duty lathe. They do not say what is included with the lathe. Steady rest, follow rest, dead/live centers, drill chuck, tool post - all should be included in the purchase. A FULL change gear set should also be available; if not, then I would walk away.
There is enough here to make me, personally, wary of this lathe. I know economics comes into play but a lathe is a "major" purchase that you don't want to do often. If I were you, I would call Matt at PM and talk over a lathe with him, along with shipping costs. If he has one that will better meet your needs then that might be the best option in the long run, even if you have to save a bit longer. Service and support after the sale is also really, really, really important and from what I've seen you would be hard pressed to do better than PM for an asian lathe. I don't have any idea what kind of support Busy Bee provides, though.
Sorry if the tone of my post seems negative; that is not my intention. Just wanted to give you an opinion as food for thought.
