Thank you everyone for the comments/concerns!

I do plan on setting up my enclosure well before I get my ball python and yes, I am actually looking forward to them being different than corn snakes. I got my corn snake as a sort of "rescue" from a closing pet shop, she's over a year old... and fiesty. Wasn't handled properly and so she bites. She's calming down, slowly, but very nervous girl. We're working it out

I would LOVE to get a morph if I can, and actually there is the Canadian National Breeders Exhibition coming to Toronto in two weeks that I will attend. I'd like to get a young python there, from a local breeder, who has her/him on f/t rats (perfect scenerio).
Being in Canada, I don't really use Craigs List... we have Kijiji. But I don't think I'd ever get a snake from there, simply because I am too inexperienced to deal with the possible issues that other's pets may come with.

I do like the idea of feeding the snake outside of the enclosure, because that is what I do with my corn and it is working for her - then again, I know ball pythons are not as hardy as corns...
I really just want a good "lap snake" (as I have heard some people call BPs), one that doesn't bite.
