You got a great deal. I have the very same model. It's new enough that it shouldn't need any restoration unless someone previously messed it up.
I also got mine at a garage sale, for $15 if you can believe that. I had just told the seller I'd take it, when another guy walked up and said, "How much is that?"
The seller explained that I was buying it for $15 (I'm frantically fishing for my wallet in the meantime). The other guy said, "I'll give you $50 right now in cash." To his credit, the seller stuck to our deal.
I didn't feel guilty about buying it for that price. If I hadn't happened along, he would have sold it to the second guy for $15 two minutes later and been happy.
