I need a new camera

I bought my camera last year before I studied abroad in Europe. I quickly realized that buying a Sony vs. a Canon was a bad choice. I had the Canon in my hand but opted for the slightly cheaper one, the Sony, and have never been more disappointed in my life. I can't shoot at night, the dial continuously moves on its own...causing pictures to become movies spontaneously, all my images are usually blurred so there's no point in me even trying action shots, and the delay is unbelievable. Needless to say, this piece o' crap camera really made this part of the project hard. I shot stills of Megan during her aerial dance class, but just couldn't get the shots I wanted. Having taken a year of photography, I have always loved it, but my camera makes it a real chore. I ended up having to make Megan pose on the trapeze rather than get her mid-air, and while I'm hoping for some pictures of her tapping, I know it's going to be nearly impossible with all the movement. Lesson learned: don't buy Sony.
