Spring bulbs are out there in abundance now. While you can always add to your collection of daffodils or hyacinths, consider some of the more unusual bulbs. Even within the old tried and true daffodils, there are some unusual options. Not all daffodils are yellow, some are white, some have orange or pink centers, some are fragrant and some aren't. By careful consideration you can have daffodils in bloom from late January through April. Most daffodils are long lived, and provided they get some sunlight following bloom, will re-bloom year after year. 
Tulips aren't quite as easy. Tulips are usually one of the last of our spring blooming bulbs to flower. Warm temperatures during bloom can cause the flower display to pass quickly, and often the leaves are quick to follow. This coupled with the fact that many of the new tulips produce many daughter bulbs, making them share the energy, flowers in subsequent years are often smaller. Many gardeners treat tulips as annuals, planting new ones every year. If you don't want annual planting, consider some of the species tulips or earlier bloomers.
There has also been a resurgence of the heirloom bulbs which tend to take more abuse than some of their showier new siblings. Regardless of which flower you choose, or how long they last, tulips are definitely the showiest spring bloomer, and worth the effort.
Crocus bulbs may not stop traffic because of their demure stature, but they are the harbinger of spring, and a reliable performer year after year-sometimes even too vigorous. Give crocus room to spread, because they will multiply. Crocus bulbs are often interplanted in lawn areas. They grow so early and are low enough growing, that they can give your lawn an early blush of flowers and their cycle is complete by the time you need to do the first mowing. 
Hyacinths are one of the most fragrant spring bloomers with clusters of pink, purple or white flowers. They also will rebloom with ease for many years, but do require annual fertilization.
Old-fashioned snowdrops and snowflakes will give you beautiful bell shaped white flowers in early spring, and will do well in a more shady location. Wind anemones will pop up early in the fall with lacy foliage, and bright colorful flowers. They aren't going to be around for too many years but are an interesting addition. Others to consider are the showy and large Crown Fritillaria with its crown of orange flowers, or the showy giant alliums, large lollipop-like flowers with a delicate onion fragrance. 
Experiment with bulbs, and you may find some new favorites. Fall planting is easy-the hard part is the wait
