So for christmas im getting a cb70 rack, and im deciding what im gona buy to fill up the last tub

I want to get an adult ball python or hogg island boa.. and im guessing i have $150 to $200 MAX to spend. it all depends on how much i hav leftover from the rack. but in the best case scenario, should i get an adult pastel ball python, or a hogg island boa? i have a connection for the boa for 150 shipped, but not sure where im gona get the pastel for 150-200 shipped. let me know what you think i should do.
