Basic morph female breeders:
Pastel
Spider/Pin
Mojave/lesser
Then with the rest of the money add some NICE males:
Clown
Spinner
Killer Bee/Killer Blast
Pied
Axanthic Spider/etc
Then throw in come normal girls for fun.
Basic females allow for you base lines then adding males with mutli genes you can use more of those genes in the male by mating them with multi females. Better bang for your buck.
But that is just my opinion. I don't have the cash so I am doing all base line morphs. If I had that cash I would go that way.
You could always get some with some nice het's also. Like het for clown, axanthic, carmel, albino, etc.
