Sherline's rotary table is nice, but small and horizontal only unless you buy the 90-degree adapter (or make one). I went with a Vertex and I'm pretty happy with it. Light duty but versatile and horiz/vertical orientation. Better than Chinese, and you can even use it as a dividing head for simple stuff. Pick up a cheap (e.g. Shars) chuck, 5" fits best on mine. You can center it on the mill.
