Mini diggers one of the best in Perth and competitive.
+1
Mini Diggers is who I (and my Builder) recommends. The site is left in very good condition - not a slap dash job.
They don't have a website but you can contact them on [email protected] or 0438331778
I haven't used them for awhile so don't know current prices but they were very competitive in 2011 and I'll check them this year for my demos
