Getting bit is something that so many people worry about, me included. I've been hit a couple of times, though I gotta say it was entirely not my Albino girl's fault (I wasn't paying attention, looked away and dropped my hand while holding her dinner on tongs. She missed, hit me, and immediately backed off.). I've literally gotten worse injuries from a thumbtack.
Keep in mind that they DO have varying personalities, though. Some are super sweet, some are secretive and grouchy, and some are very aggressive. If you get a baby you're able to influence that personality a lot.
As for taking time to get to know the animal, I doubt any decent breeder would look down on that. This is a long-term commitment, possibly longer than any cat or dog. The majority of them love these snakes and want to see them go to people who will really appreciate them, and be happy with them. Don't be afraid to ask.
I'm nothing close to an expert, but I've had 6 BPs. I'm down to one now, but I can say that they're awesome pets as long as you know how to care for them. If you've got any more questions please feel free to PM me and I'll share my admittedly limited knowledge.
