Brendon there is no doubt a rework station will make things easier. They do
not replace skill. In fact you can muck things up faster without skill. Also
they are dangerous. Be sure to keep them children as you would a gun.

Does a hot-air rework station make this all easier? I've long been toying
with getting one for SMD work.
