Two-leaded passives are easy to get with a soldering iron and a pair of curved-nose hemostats (check with friends in the medical profession- those and dental tools (picks, explorers) are really convienient to have- if you're extremely lucky you'll find someone who's getting rid of a unit- they have air/water syringes (great for blowing out small stuff) and high-speed air turbine "dremel" type things- tres useful). Just clamp the hemostat to one lead, touch a small soldering iron to the back, pull, same with other lead. They're cheap new, but sometimes I don't want to go out to get them. SMTs are a bit harder, but I've done them, too.
