FWIW, once you have an idea of what you think that you will want to make, it will give you an idea of the size of the lathe that you need. Then buy one size larger, for when your horizons expand along with your skills and confidence, you will need it.
Obvioiusly budget and space (and location of the workshop ) will determine what you buy.
A noisy 300 Kg machine is not ideal to install up two flights of stairs in a flat with thin walls!
If you feel, inclined to buy second, or more, hand, take someone experienced with you to see and check the machine. You will receive conflicting advice about old British machines vs Chinese. Both can be good and well equipped, or both can be worn rubbish! If the machine is less than perfect remember "If it ain't broke, don't fix it" Illadvised "adjustments" or "repairs" can do more damage than good! Seek advice, preferably face to face.
Every machine will have backlash, 3 jaw chucks very rarely hold work absolutely concentric. Perfection in a hobby machine is unattainable. Hobby machines are built down to a price, not to an industrial quality level.
It is said many times that you can do small work on a big lathe, but the other way round is a lot more difficult, if not impossible.
You can turn M3 screws on a machine able to swing 300 mm,600, but you can't skim a 300 mm brake disc on a mini lathe!
As a newcomer I would suggest some reading, to learn the basic principles of metal turning and tool grinding, before buying a machine.
A set of Zeus charts will be a very useful reference . I still use mine regularly, bought in 1958!
One of the standard books on turning is L H Sparey's "The Amateur's Lathe" Old but the basics still apply..
Ian Bradley's "The Amateur's workshop" is a useful guide for work in addition to turning.
Harold H has written a book on lathework, and Neil Wyatt and Dave Fenner have each written a book on the mini lathel
I find Tubal Cain's "Model Engineers Handbook" an extremely useful reference book, for all manner of details.
These books will guide, advise, teach you the basics, prevent you making mistakes or having problems, and answer lots of questions almost before you feel the need to ask them.
When you have gained skill and confidence, you can expand your library to cover such things as Drills and drilling, using Taps and Dies, Screwcutting, or Gear Cutting if you wish to progress to such things.
If you try to bite off more than you can chew you will become disillusioned, when you have problems.
Find a Model Engineering Club near you and join. Hopefully, before too long you will be able to get advice, help and/or demonstrations face to face, along with meeting other enthusiasts.
Once you have a machine, you can become familiar with it, and learn, by making small accessories, such as a Tap Wrench, Die Holders, a Centre Height Gauge, or a Mandrel Handle. Not only will you learn, as you make them, but such things will be useful in the future.
Hope all these ramblings will be of help.
