I think it has to be judged on a case by case situation. I have had both good and bad experiences with friends. I found out one thing though in the process, the pros are ALWAYS pros, and though are the people you WANT to work with. There is also a great list of Don'ts in my bag of tricks now :) So I won't make the same maistake twice, and I also won't help the ones who burned me in the past. Someone once said to me " never step on people on your way up, you are going to meet them agian on your way down" Good way to look at the buisness all the way around. SO there's my 2 cents for what it's worth.
