I am terrible about buyer's remorse. Every time I spend a large amount of money, I immediately have buyer's remorse. I can't explain it. It happened with my car, which I bought six years ago and still love. It happened with my computer (bought a year and a half ago and I still love it). Most recently, it happened with a camera.
My camera was on its last legs. It was only four years old, but with the increases in technology, it was advantageous for me to start looking for a new camera. So I did research. And then I did more research. And finally, I purchased.
And it arrived, and I had buyer's remorse. I can't explain why. It takes great pictures and was a good price and the reviews are awesome. But I just hope I made the right choice. I commented about this on my personal twitter account and immediately had responses telling me that it was an awesome camera (from people who own and love it), so I'm sure that I will love it once I get using it.
I just wish I didn't always have buyer's remorse!
