Ok, thanks for the feedback! I think I was so traumatized by the mealybug thing, I have been a bit paranoid of having that experience again!
I am pretty new to this, so I can't say if I have any trusted suppliers yet, but I will say, I picked up a batch of new plant babies on the weekend and repotted them all, and they all had great looking root systems, so maybe I can add that supplier to the 'trusted' list
