Recently found a Fizik Arione saddle w/Ti rails on CL for $40. New. Couldn't pass it up as it gets great reviews and is normally ~$120. So far, its great and a huge improvement over my Bontrager Select (stock with my bike). I'm an XC rider, long days, and some bikepacking so I wanted something that could go the distance for 4+ hour rides (and sometimes with a pack on my back). This thing is super comfy as the wings flex with you. And its light as a feather. I would recommend it.
I had my eye on a Brooks as my dream saddle (B17 narrow), but the best deal I could find was $85-90 on e-bay. Not bad for a Brooks, but still too much for me. Still it would certainly outlast my bike and possibly me. If you have the bills to pay for it, I would go with a Brooks. Otherwise, I tend to peruse CL and then search items of interest plus "review" to see what people have to say about them. Loves me some internets for stuff like this. Good luck.
