Welcome!
The lathe that you choose will be decided by a variety of factors.
Budget (Should include provision for measuring equipment, and tooling and before too long some Taps and Dies.. And as time goes on, you will want to buy extras. Not necessarily all at once, but as the need arises
Space, (A garage should provide sufficient . But insulate it well. varying and low temperatures encourages the rust fairy to visit often, and for long periods! )
What you want to make. (FWIW, my advice would be that having come to a decision, buy something a little larger, ready for when you become more experienced,and confident )
Don't rush things.
Consider carefully, and seek advice by finding and joining a local Model Engineering Club, as well as seeking opinions on here.
