Shawn,
My advice would be to spend an afternoon doing a search thru the archives here, as there is soooooo much more info in the old threads than can be answered here in a couple posts. You mention your getting a Jet mini lathe, is it a machinest lathe, or a wood lathe? That answer will dictate your tooling needs for that item.
I have bought quite a few awesome tools, and then bought quite a few duds that never lived up to the hype, or expectations. The biggest factors, IMO, first, what do you really want to accomplish in the end run? Second, What can you afford, Thirdly, what will get you by until you make some money back to be able to buy better stuff.
If on a limited budget, and only want to do repairs, Harbor freight has some good items, and Mueller's has tools and equipment for the lathe you now have for decent prices. If you want to build cues, well, start saving, and looking around for good deals, and then go see Chris Hightower.
As an example, I use about 12 Harbor freight drill chucks with a MT2 arbor preset up with the various bits, and they are more dead on then the $100 one's that I bought when I started, and they cost less than $10 each. Even if one is off slightly, I can throw it out and buy another. I have a keyless drill chuck, with arbor, that I bought that as soon as it gets any shavings, dust, etc. on it, it jams up, and won't hold the drill or endmill centered. It's a big name tool and cost me a lot more than my HF ones, but I rarely use it because of that problem.
Well, good luck on your quest.
Dave
