Jared;
You didn't say in your earlier post where you were planning to buy the psi utility chuck from, but amazon sells the psi chucks at a substantial discount, and with free shipping. You would pay $79.95 plus $8.00 shipping at psi for the utility chuck with 2 sets of jaws, screw chuck adapter, and mounting adapters for 1" x 8tpi and 3/4" x 16tpi. At amazon.com you can get this:
http://www.amazon.com/PSI-CMG3C-Mini-Lathe-Chuck/dp/B0006OC3B4/ref=sr_1_8?ie=UTF8&s=hi&qid=1198900207&sr=1-8
I THINK this is the same one I ordered from them a month ago, but amazon has reworked all their psi listings recently to correct some glaring errors. This chuck is the chrome body which will not rust, has 3 sets of jaws, and "if" it is the same one I have will screw onto a 1" x 8tpi lathe without an adapter, which eliminates a fairly significant, IMHO, nuisance. with no shipping and a very simple return policy if you don't like it.
I don't know if PSI fixed the issue with the tommy bars bending that is referenced in the feedback for this item, or what, but I have had NO problems with them on mine. This is probably the best entry level chuck you will find, and will do most things a mini lathe owner would want to do.
A scroll chuck, I.E. one that uses the two tightening, or "tommy" bars is usually considered more complicated to use than a "key" chuck that uses a single tool to open and close the jaws, but I have not had any problems holding my workpiece in one hand and closing the jaws with the other. My opinion is that the tommy bars give you a better feel than the key for when the piece is tight.
