Phoenix managed to do a planted african tank, and YMIR also has a nice planted tank with dems/peacocks and a few others kicking around in it.
I would recommend the dem/yellow/peacock (colony of one type if you want to breed) because I like it, it looks good and works well in a smaller tank. It is also unlikely you will end up with cross breeding and could breed all the fish in there. But to me it really depends what you like more than what you can breed to make money
You can sometimes get really good deals off trademe I got a 250L all in one setup off trademe that came with a chiller which I sold and the whole setup including an external cost me $65..
