I got my Brooks B17 for $80, and now that I've had it for a few weeks, I can say it's so comfortable I would easily spend over $100 for it. (Don't tell Brooks, though )

Even poorly adjusted it was comfortable. Once I got the angle and saddle height properly dialed in after a ride or two, it became even better. And now that it's really getting broken in... aaah. Money well spent!

OP, do yourself a favor and spend the extra $15 for the Brooks if you're already looking at $65-ish saddles. If you still have some doubts, spend a tad more, buy it at wallbike.com and you can take advantage of their return policy if you're unhappy. Or find an LBS that would do the same.
