Don't regret it one bit. We got married in our living room (our state is odd). He got a cheap ceramic ring because of his job and I got a thin gold band. We paid just under $400 for rings, a white dress for me, the officiant, and dinner that night. Its been almost 3 years, no regrets. I'm exactly like you, I don't care to be in the center of attention and we didn't want to spend money.

A friend did take professional photos for us, which I do cherish. I sent out photo cards that said, "We got married!" And included the professional photo in it.

The following summer, we had a party at his parents place. We rented a tent, table and chairs, and had a pig roast. Our parents paid for it. We felt a small bit of pressure from our family to "do something" for our wedding and our parents were kind enough to pay for the reception. And it was nice, a way for us to introduce our spouses to extended parts of our family that we don't frequently see. My husband really enjoyed the reception and I can hear in his voice he was glad we did it when he talks about it.

So yes, I cherish the intimacy of our living room. But photos and a reception months later were also nice.
