I bought the 4 jaw Indian chuck off ebay, initially I was disappointed as it was very rough movement. I stripped it down and used a small needle file and did a small ammount of work on the contact surfaces and the edges. Honestly it is fine now, I suppose it's the old story, you get what you pay for.
I've never seen a chuck this size and it was a bit of a shock when compared to my 4" mini lathe chuck
