This is another I ran across that is a casting kit that looks pretty nice. These folks have other casting kits you may be interested in as well. I purchased the cross slide for the Atlas lathe from them (A-11), as well as the filing machine kit (MLA-18). They are nice and their prices are reasonable. I plan to purchase the collet chuck at some point.
It's never too soon to learn. I personally would go with the one Charles built. He is a master at doing these things. He will be there every step of the way if need be. Many of us have 9X20s and we will all be there for you,
