Quarantining a CB hatchling from a well-reputed breeder?

I never used to quarantine my balls, as I always pick up my stock either from very good friends, or very respectable breeders, but a year ago, I purchased a morph at the CRBE from a very large, very well known breeder just across the border from me (I'm in Ontario) and the animal exhibited signs of an RI a day after she came home.
ALWAYS quarantine.

a solid yes, doesnt matter where is comes from it is now part of my collection and I am not going to take chances with my snakes

I QT around 3 weeks. I have had balls enter the rack quicker than that though. A fecal test is done on all new snakes before they enter the rack after at least 2 weeks of QT.

There is only 1 person I buy from that I dont always quarantine stuff from, and she lives about 2 miles from me and I am at her house visiting and talking snakes with her on a very regular basis. I know her and the quality of her animals extremely well and she is my only exception. Generally quarantine for a minimum 2 months from anyone.
