since you never owned a ball ........and I am not sure what snakes you owned at all........
I would say get a normal female and get some experience at keeping and breeding......
after you know how to breed and keep and get babies eating and all........then get some more females(keep your own baby girls) and then after they are a year old get a male pastel........they will be cheaper still by that time......heck..mybe free the way people think they will drop.(more like $200 to $500).......
have fun....balls are cool ...even normal ones........
