I'm a keeper at the moment, rather than a breeder, and I've looked at thousands of pictures on WOBP and Morphmarket, pricing out what I like vs. space I currently have available.
I started with the basic morphs I really liked that were popularly/easily bred into BPs, specifically spider, calico, and leopards in my case. From there, I built on them with traits I liked - bright/high white sides, cleanliness of pattern, etc. Then I started looking at price and what was available. Cross-checked breeders, etc. Look some more. And on and on.
There are so many options in this market, that it really pays to look around and find out what you like. It may be something completely different that what others will show you (I love bright stuff and high white sides, but my husband is more a fan of naturals and dark colors... so I know at some point I'm going to have to build that in somewhere for his putting up with me and my hobby lol).
