I know some people think LDs and OBEs are different things. I agree that they can be different experiences. When I WILD, I get more of the classic OBE type of experience, and when I DILD, I get the typical LD. Personally, I see them as just different types or levels of lucid dreams, but different experientially.
Studied from a physiological level, they are identical. Your physical body is doing the exact same thing during an OBE that it is doing in a LD. From that standpoint, there is absolutely no danger of somehow accidentally going OBE and suddenly cutting some silver cord, and never being able to return to your body. I've died in OBEs, died in LDs, had energy sucked out of me in both, been shown the face of god, been sucked back into my body, ect. ect. I don't believe there is any danger.
Also, there is no proof that OBEs are real. By that, I mean, no one has been able to succeed in experiments to prove they have a connection to the waking world. Its pretty simple to have a friend write something on a piece of paper, and then have you try to read it in your OBE. Unfortunately, nobody has ever succeeded in doing this.
That being said, I don't discount the possibility that all dreams, lucid, OBE, or otherwise, are real on some level. I still question the reality of my consciousness in my waking life. I think its foolish to be overconfident about your knowledge of anything in this wacky world. I don't assume my silly little, perception based, human brain is smart enough have anything totally figured out. I try to keep an open mind, and respect the mystery of both waking life and dreaming life.
There's no reason you can't try both OBE and LD, and see for yourself. Its definitely a real phenomenon, so lets all try to figure it out through experience. Let your own experience be your guide.
Have you guys checked out the Beyond Dreaming section?

Its (supposedly) there for people to discuss stuff like this without getting flamed by skeptics.
