Getting started with the basic tools

First I like using the chuck, the cheapest one is the Penn State Baracuda, this is the best deal right now. 

Or if you want a smaller chuck that would work for boxes and small things.

Next tools, I like the mini set for turning small things. 

And possibly some bigger tools. 

Then a sharpening system the One Way Wolverine, or just a little cheaper but maybe not as solid.

A slow speed 8" grinder.

Past that you will find many other things you may need as you get farther into it.
