how about an Albino White-Lipped Python or Albino Woma or Black Head Python? i'm not sure about their requirements for your thermostat question, but these are very cool and unique options.
also since you like both Albino and Lucy's, how about a Red Eye Lucy (REL). they're Albino Leucistic's.
Those White Lipped Pythons look really cool. I like Woma's I will check out the temp requirements for these 2 species.
