Best Place to Draw Blood?

[PythonChick]

I now work at a vet lab and I get all my blood work done for free, so I figured I'd take advantage of a good thing and get some work done up on my snakes.
Where can we draw blood from a Ball Python? A few of the people on staff are Licensed Vet Techs, and have drawn blood before, but not on snakes. We did some reading and the book says the heart! They really don't want to have to do that. Where is the next best place to draw blood? Does anyone have a diagram on how to do it?

Thanks!

I have also read that the heart is the best place to draw from in snakes, but like you, I have never done it and I don't want to do it.
