the sunrise blvd pets warehouse had checkerboards for 5.99 , they are not as colorful as cockatoo , but not nearly as expensive and more can be kept in one tank. You may wanna contact Frank from http://www.franksaquarium.com/ and ask if he can get you some apistos if you prefer them.
I just picked up some balloon rams from pacific in china town 3 for 17$ great condition eat like little pigs great color.
they had several different types of cichlids not sure if they had the cockatoo but def worth a call
There are a few breeders but they are not in the forums.
Sometimes I can get the double reds in. Aside from those I have access to standard german/gold/electric rams. I don't want to ship fish out, but you could pickup from me.
I can't offer breeder pairs, you'd have to purchase a handful of them to get couples.
There is someone that went to a NJAS meeting that I spoke with who was breeding some yellow and orange ... worth a check on the Jersey page!
