Don't be tempted by the Brooks wannabes like Gyes or Velo Orange. Get Brooks, I believe the quality is higher. (I bought a Gyes last time...it will be my last time.)
My personal favorite is the Champion Flyer, basically a B17 with springs in back. Every Brooks I have owned was better with gentle conditioning and about 500 miles. The only saddle I like more...is on my recumbent!
