You can learn a great deal from researching on the Internet, but without actually making chips it's all theoretical knowledge. You may find a better deal by waiting but you will loose nothing by going to look at machines, especially if they are under power and the owner is willing to demonstrate their operation.
Knowing what I know now this Jet, or something like it, would be a good candidate for starting out with. I bought my Star with very little knowledge and only $300 15 years ago. It served me well in my business for years but only recently did I actually start using it as designed and there are many things I would rather have than the taper attachment.
If you haven't contacted the seller I would do so today. It's probably already spoken for but if not I would go check it out, there are threads on here about what to look for but if it's running and the carriage moves smoothly it will probably be okay. At that price you should be able to get your money back if it's ultimately not what you need but there are many, many basic skills to master before you get to your ultimate goals and a manual lathe is the right place to start.
JMHO,
