Well as far as personality goes, they are completey different IMO. Boas show so much curiosity and "playfulness", while balls are more timid and lethargic.

As to the 75 dollars thats pretty cheap, so be careful. Maybe even do a check on Fauna to see if the breeder pops up.

Hog X's are extremely popular right now (dont know why) and some look like pure hogs, some look like normal BCI's.
