I have already seen the new forms/addendums that will be used here in Arizona, the common one for this will be the Seller Compensation Addendum.The one thing that might happen in your discount buyer agent scenario is you might get a buyers agent who agrees to a lower commission and then the listing agent is offering a co-broke that is higher than he agreed to, well now that buyers agent will only be able to get paid the lower amount he agreed to and the listing agent will keep the remainder, so listing agents could end up getting paid more.As far as your question on what to pay an agent, I view it similarly to hiring an attorney, there are discount attorney's and they might be okay for some people in some circumstances, or if you know the proper procedures and deadlines then maybe you do it on your own without an attorney.

Ultimately it depends on what you feel is right for your circumstances right now.   

Unfortunately I work offshore and I leave for weeks at a time, so over the course of one year, I am gone for at least half of it. 

Unfortunately I can't use the boost option yet because I'm not a Premiere Host.
