Another great way to try it out the first time is to go down to your local game store. Most stores in my area seem to be 99% Magic the Gathering nowadays, but I still find that most stores have a regular D&D night set up. They'd almost definitely let you drop in for a night to try it out.
Chances are you could use probably share a Player's Handbook with someone the first time, if you haven't gotten one yet.
The only thing you'll definitely need is your own dice. No one will share those... bad mojo!
