I'm kind of in that same boat. Got a normal for our son for a pet, and caught the bug.
I went and picked out our snakes from a breeder last week, and will be picking them up next month. Gave lots of thought to what to get, but this is what we decided:
1.1 Het Caramel Albino
0.1 Het Ghost
1.0 Pastel (Het for Ghost)
0.1 Pastel
Plan is also look for probably 2 more females- a spider and a cinnamon, and maybe another male pastel to breed to those. I figure that should be a good start for a really nice collection.
