I've been using Koh-I-Noor Rapidograph Technical Pens since 1969. My aunt bought me my first set when I was 12 and I have used them daily ever since. I love the fact that I can mix my ink colors to match my watercolor or my wardrobe and use "Pelikan Drawing Ink A" almost exclusively. Though the inks made by Koh-I-Noor and Winsor Newton are satisfactory.
If you are a beginner, I would NOT recommend purchasing anything smaller than an 0 (0.35 mm). Even as a professional I find cleaning a 4x0 to be a challenge. I work most often with a 2x0, and find them to produce the smoothest flow, if kept clean.
I used Porcelaine 150 about 14 years ago on some glasses; they have been washed over and over in the dishwasher, and the color is still bright and beautiful. I did bake them in the oven as the directions specified. This is a great product!
