Recommend a Logitech G305 Clone

Hi everyone and thanks for helping.

I'm a fan of the egg shape of the Logitech G305 and am looking to get a new mouse that isn't weighed down by AA batteries. I did some research and found the following:

1.) MCHOSE G3 - £50
2.) Attack Shark G3 - £25
3.) Attack Shark G3 Pro - £30

From what I've read the MCHOSE is the best of these mice, but there's a surprisingly big jump in price between them (maybe a problem with living in the UK?).

Do you think the MCHOSE G3 is worth the extra cost?
Am I right in thinking that the Attack Shark G3 is generally worse?
Are there any good budget G305 clones that I've missed?

Any help would be fantastic!
