I took a beginning bowl-turning class at Woodcraft a couple of years ago. I turned on a Nova 3000 all day. Not a bad lathe. Not a really great one either, IMHO. I thought it to be excessively noisy. Our club also has an older Nova 3000. It also seems to be excessively noisy. And during a turning demo the motor shaft broke. There have been some threads on this NG about this defect. Personally, I feel it is a bit too easy to apply too much belt tension, causing premature failure of the motor shaft. I'm still turning on a Jet Mini. Since I'm not even in the category of lathes you are looking at, I should probably keep my opinions to myself. But, I feel the Jet Mini is a better small lathe than the Nova is a larger lathe. (Did that make any sense at all?) Good luck in your quest. Let us know what lathe you settle on.
