If you are undecided... that MIGHT be your intuition telling you something. My husband and I rely on this second-sense to guide us all the time. We buy on Craig's list, periodically, too, and when it doesn't feel right, we pass.
When I was dating (LONG ago), I would go to my friends and ask them what they thought about my boyfriend; when I married my husband, I didn't ask anybody. I knew. Not the same, but it works the same way.
I like the idea of having the woman do the burn test for you... if she will. Then you will have more clear information.

"You'll know if it feels right."
