Looking for a brand new mini

Hi there, this is my first post so, be nice please :).

I work with a small trail building/earthworks place in outback australia, and recently was tasked with looking at a new fleet of compact excavators, ranging in size from 1.7t to about 6t.

We have narrowed down the choices to Bobcat, Caterpillar, Kobelco, Kobuta, and Volvo. I have experience with Volvo, Cat and Bobcat and they all make awesome machines.

Anybody got any experience on these machines are the ups/downs of them? Thanks.
