I absolutely love the Calphalon 3-qt covered pan.  I use it virtually every day because it's perfect for almost everything.  It's a great size and holds a lot, but isn't so cumbersome that it can't be easily washed.  The lid fits very well and holds in steam and liquid, so I often use it for braising vegetables or meat.  The sides are high enough that it avoids much of the splatter that can occur while things are simmering (and I love anything that reduces clean-up!).  I also love that this pan is non-stick, and I never have a problem with things sticking even when I don't use oil or any kind...
