You sound just like I did. Except I didn't have the brains to read such a forum and post the question first! Wish I did.
Perhaps you should read the post I just posted above. I never had the 'is something missing' feeling either. I think it was more of a 'should we or shouldn't we' feeling if that makes sense. Anyway, perhaps my post will help wity your decision making. Hopefully you'll be one of themillions happy if you have another. Good luck!
