In my opinion, do not start off with a mini lathe. I know that's the common advice, start with a mini lathe and then sell it to buy a bigger one if you like turning.
But, have you noticed that no one tells you to start off with a 9" bandsaw or a tabletop tablesaw to see if you like it?
To me, it makes no sense to buy a mini lathe if you can afford one of the entry level full sized ones. I haven't checked prices for awhile, but I think the minis are around $300.. I bought a full sized delta one for around $500.. Keep in mind that the full sized one can do everything a mini can do (except be portable). Keep in mind that the used minis that I've seen don't seem to have that great of resale value.
If you like woodworking, you'll like turning.. No sense in buying a mini lathe to see if you like turning.
