I know how you feel. I had issues with finding the right saddle too. I had ridden for over a year on the terry butterfly but when I started to go on longer rides(anything over 40) I was miserable. I tried a serfas seat out when I did a time trial recently and that was a total disaster, the plastic part in between the cutout tore me up.
I tried out the specialized jett and found it too hard on my sit bones. Right now I'm riding on a saddle that Kaian was nice enough to give to me, it's a LeMond with a cutout and is nicely padded in the nose area. I'm not sure it's my "perfect" saddle but it sure is comfy compared to others I've tried so far.
I don't really have any advice other than maybe try to purchase your saddle where they have a good return policy, that way if it's not working for you, you can return it, otherwise you might be stuck with an expensive mistake.
