I love Gold Marlboros and Blue Heavens. Both types will be going in my new tank. As for a favorite breeder, I'd recommend www.GreatLakesDiscus.com. I haven't ordered from their yet but I will most definately do so. There strains are wonderful, prices excellent, and staff knowledgeable. I have talked to Cary, the owner, and am 100% confident with the hatchery. *celebratesmiley*
