Here's a little video clip of my 1.0 Lemon Pastel (June '08) and my 0.1 Mark Bell Pastel (Jan '09). Personally I am a big fan of the Mark Bell line of Pastels. You can see why when you look at the video. The female in the video is getting close to 2 years in age, with no signs of browning out. Not trying to sound like a prick, but she's the best example of a pastel I've ever seen, especially one that's not a super.
