For those that don’t get the 5-a-day Woodcraft sales emails: http://www.woodcraft.com/product/150699/nova-g3-chuck-package.aspx.
I don’t own one, but my understanding from research and word-of-mouth is Nova chucks have a good name/reputation. Note: you would also need to buy an appropriately sized thread insert(s) for the lathe(s) you plan to use it with.
