monochrome

I picked up this doujin on a whim with several other items from Comiket 75. I had never heard of Toshimasa Komiya (小宮利公), but the Hatsune Miku picture on the cover caught my eye, so I bought it ^^; Has anyone else heard of this artist before?

Occasionally, I like to pick up monochrome doujinshi from certain artists. Sometimes, I do it on accident. But fortunately, KEI aptly titles his doujinshi with names like MONO 02 so I don't have to guess about it being in color. This one is a surprisingly thick 50 pages long. Would you buy a black and white doujinshi from your favorite artist, or is it just not worth it unless it's in color?
