Actually, I was mistaken... I got it for $20 on ebay. If you have a 1991 or prior Civic, check out Ebay item #110307523434. Newer Hondas require a different tool, but I've seen those for less than $30. Currently, I'm considering picking up a universal holder because my Tundra is next in line for a timing belt, and if I get too much practice at this timing belt thing, I might end up having to change them for friends and family...
I've found one of the universal ones here for cheap.
