Hi discus_2013,
Finding quality GBR can be a challenge but is definitely worth it; finding ones that are also bred locally it like winning the lottery. I have purchased high quality GBR's in the past only to loose them because they were bred and raised elsewhere and were not used to our very soft NW water conditions.
Fortunately GSAS has at least two members that I know of that breed quality fish and one of those members sells them to a well know LFS in Edmonds. I picked up mine from another breeder in January of 2015 at a GSAS monthly auction; six beautiful GBR juvies that are all going strong today.
