I like the Merauke and Biak's. I just like the lighter, bright neat looking greens. I like the Green and yellow look of the Biaks. As much as they change color, it's going to be hard to pick... lol.
As far as budget... I can't afford to spend 1k on a pet snake... A local box pet store recently had a nice Biak that I liked for 299. Is that a decent price?
