Kind of depends on the type of riding you do and your personal preference. I prefer drop bars for all riding, except of course mtb. If you do decide to try them, you might need a new stem (to fit the dia of the bar and also to position it appropriately), and of course shifters, cables, bar tape... Shifters need to be compatible with # of gears and cable pulls for both DRs and for the brakes, etc... Alternatively look around and buy a used or new bike already set up with drop bars. That may be simpler, easier, and if used, possibly even cheaper.
