I am so surprised there aren't more Copic fanatics jumping on this thread. I am totally in love with my copics. I tried the spectrum noir and HATED them. They don't color nearly as smoothly or seem to blend anywhere near as smoothly as the Copics do. And they dont have a super brush tip, which I think makes the copics the best. In this case I really feel like you get what you pay for as far as quality and color variety.
Want to fall in love with copics? Then search the gallery for Copics and look at all the AMAZING creations. Even the least "talented" Copic users can make gorgeous creations. It takes a little practice to learn the blending techniques but anyone can do it.
And they are way way cheaper than $8 a marker. I get all of my copics from markerpop.com
