How bad is your leak? My 86 had the same thing, there would be a puddle about 4-5" across under the car after parking overnight. I put in Advance Auto Parts power steering fluid, kept replacing it with their el-cheapo brand, and the leak pretty much went away. You may want to try that to see if it helps you, too before paying to have it repaired.

When the leak started, my power steering fluid looked muddy; once it got to looking normal, the leak pretty much stopped, except for a few drops overnight.

As far as the repairs, you should be able to change it out in your backyard with a used unit from a junkyard (might leak) or a new one from a parts store/dealer. Just make sure that once you've swapped it out, you fill the reservoir and turn the wheels all the way to both sides, refill, and repeat, in order to make sure the system is full.
