Whenever I've done this, the solder sucker never gets enough solder
out to just lift the chip away, but a little sideways wiggling of
each pin from the back side of the board with a needle nose pliars
will break each pin free of the little remaining solder.  You can
then lift the chip free.  Much simpler than a special device to 
heat all the pins at once.

Good luck.
