What you might want to do is think about what male you plan to someday get, then pick females based around the male.
For instance, you said you like Ghost crosses. What is your favorite Ghost cross? Whatever that is, plan on getting a male of that cross down the road, and build your females around that future male.
For example, If you like Pastel Ghosts (one of my personal fav's) then plan on getting a Pastel Ghost male down the road, and for females you could likely afford a baby Pastel Ghost female, that way you'd produce Ghosts, Pastel Ghosts, and Super Pastel Ghosts. Another option for a female would be a Spider het Ghost (if you cannot afford a Honey Bee). From that breeding you could get Normals, Pastels, Spiders, Ghosts, Pastel Ghosts, Honey Bees, or Humble Bees.
Or if you decide to work with Pieds and eventually plan to buy a Pied male, work your females around that. With your budget you might not be able to do alot of Pied females, but perhaps some hets, like a Pastel het Pied, Cinnamon het Pied, Spider het Pied, etc (not saying all of them).
I highly recommend you do not get different kinds of recessive females that would make it difficult down the road to find a male to work with all of them, or you'll be stuck buying different males for the different females.
You seem to like Recessives, but if you are open to Doms or Codoms you'd be more flexible in matching females up with a future male.
Best thing to do is pick your favorite morph, then work a project around that morph.
Hope that helps... Good luck with your decision!
Here is my Pastel Ghost. I love her to pieces and she just keeps getting prettier and prettier. She'll be paired with my Honey Bee when she gets big enough.
