Looking for a mouse with buttons on both sides.

Hi,
I'm looking for something similar to the G Pro Wireless, but with at least one additional side button.
Having buttons on both sides is a strict requirement. I need at least 2 on the right side and multiple on left side (3/4 or more), but i don't want tiny, tightly packed buttons like on the Scimitar elite, because my thumb is too big for that kind of layout.

I just find it much more comfortable to use buttons on both sides.

So far, I've found the Cougar Dualblader, which seems to fit what I want, but in my country(Poland) it's only available from sketchy store with strange return policy.

Any recommendations?
