Harbor freight has some inexpensive lathes for $100ish.
And Sorby just came out with the Turnmaster tool which will accept 3 different shaped carbide cutters.
While you are shopping get some safety glasses and a dust mask, some of the woods are BAD MOJO to breathe.
I gotta go with fortytwo on the youtube vids, they are great for ideas.
But...I would also suggest that you go to your local woodworkers outlet to take a
shop safety class before you start playing.
Just make sure you have fun.....
