Yoga.......to do or not to do?

I really like yoga. I love the feeling I get when a class is over and I feel flexible and relaxed. The problem I have is that I usually end up getting hurt or something b/c I try to be like all the other yogi's who practice everyday. So the question is.......is yoga good for running.
According to Runner's World "Yoga realigns the body and releases tension from connective tissue," (Sharon Stocker, mind/body editor of Prevention magazine and a veteran yoga instructor) . The musculoskeletal realignment comes from stretching and an emphasis on proper posture.
We all know that running causes microscopic tears to the muscle fibers and when they begin to heal, they tend to bunch up and shorten if there's no stretching. Also, with our daily stresses at work, at home, and trying to squeeze in a workout our muscles become tight. The result: misaligned muscles are stiffer and less efficient which is something you don't want after all the hard work that's been done with training)
Yoga can help flexibility and strength so practicing yoga a couple times a week is very beneficial. And the result is more flexibility and reduced injury risk. And better overall strength can only help your running.

But let's not forget the cost of yoga. Yoga is expensive. If you dropped into a yoga class the price is about 10-20 dollars. If you buy a package then the cost will decrease to something like 10 dollars a class. That cost will add up and that can be difficult to afford in these hard economic times. There might even be a time constraint. A small solution could be buying a dvd and doing it at home. Maybe a group of people could get together and everyone buys a yoga dvd and you could take turns. Finding what works for you is important.

I've practiced yoga a couple of times this week. It's easier when I'm tapering to get yoga into my schedule. My goal is to integrate yoga into my training schedule whether I'm doing it at home or if I'm going to a yoga studio
