Suggestions?

So, I want to knit Joseph from Knitty's spring issue. However, I can't seem to find "Colinette Columbo" anywhere - even the Colinette site acts as if it doesn't exist. Does anyone know if this goes by a different name , or if it is so completely discontinued that it's ceased to exist? If it's the latter, does anyone have any suggestions as to what make a good substitute for this sweater?
