Replacing the slot is not that hard, you do need a desolder pump and a small tip low wattage soldering iron. (try not to use de solder wick as this can overheat the board and remove the tracks)
Remove the solder from the 4 pads round the 2 sides of the slot, then gently heat the pad while lifting the slot gently with a knife or screwdriver, this should remove the 4 retaining pads. open the metal top of the slot and strip bits away, then you just have the pins floating around. hold each pin with a thin pair of pliers and heat the pad and remove them one at a time.
Place the new socket on the board, it has locating pins so will locate into place. (if the pins on the new slot are not straight and in the right place use the pliers to straighten them now - 5 mins now makes things so much easier) Take some solder and heat up each of the 4 side pads and fix the unit to the board, then start at one end and solder each pin, if you get a bridge of solder use the desolder pump to remove it and start again, work your way along the slot from one side to the other. It should be done!
