Real estate agents

At the risk of attracting flames for posting yet another “where’s the best….” thread, (and yes, I have used the search button but would appreciate hearing some recent experiences) I’d like RiotActer’s recommendations for a decent agent to sell our Gungahlin house. We’ve found the place we want to move to and need to sell our current home promptly. No time to muck around trying to save commission doing it ourselves, just need someone honest, professional and good at their job. Ideas? And what about commissions? Do they vary greatly between agents? Is it OK to bargain?
