If you're not comfortable doing the soldering your self and you have someone else who can do it, invest in the beer
Soldering components on is easy enough (although, it can be messed up), but removing the old components is the tricky part. If you don't know what your doing, you can damage the board pretty easily.
I do all my own repairs as well as a lot of other Electronics work. I'm sure a lot of others on here do as well. You can too, with a little practice, just take your time and you might practice on something you arent afraid to damage first.
I bought a Digital Solder station of my own from Newark Electronics, but you can get an inexpensive unit from Radio Shack.
