CSS3 is getting mature and as a front-end developer, I have been using fair a bit of it such as box-sizing, border-radius, text-shadow and gradient. It's a brilliant solution because those CSS3 effects are quite common in design. For now, the only thing you have to worry is IE 7 and 8 support. Sometimes I even use CSS 3D transform to spice thing up a little bit, but you do have to make sure it can be degraded gracefully like this tutorial I wrote few week ago - Create CSS 3D Transform Card Flip Gallery.
I like online CSS generators, for example, CSS3 gradient generator's user interface. It always come with color pickers and generate all different CSS gradient codes with browser prefixes.
