8k Ergo Gaming Mice under $50?

Looking to upgrade from my old 1k mouse. Not sure if higher polling is worth it but might as well get it now. On somewhat of a tight budget. My hand size is 19.5x11 and use palmed claw. I've had good luck with EC2/Xlite shape while Deathadder V2/Zowie S1 felt too big. Open to trying out new shapes. Main use will be competitive gaming. Prefer something lightweight, very low latency, consistent reliable performance, little or no software and clicks that aren't heavy. Any suggestions?
