my LBS has a trial Saddle program with Selle Italia where you can take home a used or slightly blemished saddle from their tester fleet, and make sure it's a good fit before you purchase. I talked to them about it, and apparently Selle Italia supplies them with the test saddles, so I imagine other Selle Italia dealers also have a similar deal. When you're trying to sell $100 saddles, this program makes a lot of sense.

Call up a few of your favorite LBS and see if they have a trial saddle program.
