Logitech MX518 mouse but with more buttons?

Hi all, I currently have a Logitech MX518 mouse. I am really happy with it, had it for years and its still great but would like more buttons I can configure in games.
What would you guys suggest as a replacement?

Cheers guys, some nice options there. I like both the G600 and Nyth. Will do some research on these 2 I think
