What mouse to buy?

I've been using superlight since it is released and got the feeling that smth wrog with the sensor, feels like input lag not smooth, i tried to play another mouse and there were no this problem.

Currently i'm not sure what to buy: superlight 2, pulsar x2, Lamzu atlantis/maya.

I don't really want to spend lots of money, but want to get smth better than superlight 1

Any recommends?
