Adding to the chorus about the Misto - I actually put TWO on my registry so I could have one with olive oil and another with canola. (DH didn't understand why I had 2 and "confiscated" one. I'm still a little steamed about it because I want it back!)
It really does work!
Also, I don't know what kinds of pots/pans you're using, but there are some great nonstick options that aren't Teflon, including cast iron (seasoned properly, cast iron is AMAZING), enameled cast iron (will need a little lubricant) and anodized aluminum.
