I probably tried at least 10 different saddles before I found one that fit me great. I've since installed the same brand/model of saddle on all of my bikes. I have bought most of mine on eBay for very reasonable prices, ranging from $10-30, for a saddle that retails for $100 or more (Fizik Vitesse). A lot of people buy bikes and find the stock saddles are uncomfortable, so they sell them on eBay or Craigslist. If you watch auctions, you can often pick up almost new or lightly used saddles for bargain prices.
