Johnathans, the lathe that you showed a picture of looks like a Southbend 9C, it's a 9 x 19. This is the bottom of the class of 9 inch for SB. It is called a workshop model. This machine does not have a power cross feed. It will thread and you also use the half nuts to power turn on the longitudinal axis. The spindle hole is 3/4 of an inch. This machine will take collets but only 3C's which are only rated for 1/2 inch. When threading you need to change the gears manually. I believe it will cut somewhere around 45 standard threads. As already indicated, if it is good condition you can get a lot of work done. Even though it is a 9C it is a darn good lathe. It just does not have all of the extras. If you decide to pursue this lathe make sure it has all of the change gears. Also look to see if it has a draw bar, collet holder, thread protector and collets. They are all available after market, but this is where you get nickeled and dimed. If it is decent shape I would expect to pay anywhere from $300 to $650.
Or you could wait and find something with a lot of tooling and capable of larger work and also have a quick change gear box.
