I replaced mine a few years ago, and at the time I was super new to soldering and I still had no problems. Was able to get them from a random supplier on the east coast, I ended up getting a few new meters as well (can't remember on top my head the supplier but they were great to deal with, had a few rec/play pcb cards for cheap as well). Just go slow, take photos of every piece you remove as you go. Like J.Harv said, just be gentle and careful when soldering and you will be fine.
