If you can afford both and if those are 2 projects you really like than go for both.
As for this
Thinks about it this way I would not drop several K with someone that I never heard of even if the animal is a visual. Everyone has to start somewhere, you still have time before hatching anything and a good reputation is something you need to start working on now hets or visuals. Regardless of the animal you try to sell you will need to start building a reputation, this does not happen overnight it takes works.my concern is who is going to buy 100% Het ghosts from me if I do not get visuals?
