Should I get a DSLR?

Photography used to be something for "other" people. I spent most of my childhood, teens, young adulthood, and now avoiding the camera -- by which I mean both avoiding taking photos and having photos taken with me in them. The latter part, being the subject of photos, is still something I don't care. However, I've been getting into photography and photos slightly.

It's an interesting art form that is open to just about anyone. No need for paint or brushes, pens or pencils, all of which I suck at unless you count childish doodles. I now have one more camera than I have time to use, but I am still looking into getting a DSLR. In the back of my mind, it's a toy and a gateway into "real" photography -- probably more about the expensive toy part.

Regardless, I didn't know where to start without splurging on a $500+ camera. Some googling and online reading was done, no books have been read as of yet, and I have found one very interesting website.

Aperture, Shutter Speed, ISO?
Turns out that Canon, I believe, created a website (Canon Outside of Auto) a year ago to show someone the absolute basics of photography. The site is interactive and includes a relatively short lesson on stuff like shutter speed, ISO, aperture, exposure, etc. Most importantly, there is an interactive camera simulator to allow one to experience how changing those settings affects a photo. I had a lot of fun with it my first run through and it was exactly what I was looking for in an introductory book or course.

Obviously, it's likely a site to help Canon sell more cameras. The joke's on them because I stick to Canon cameras out of familiarity anyways.
