I prefer the glass tops as well, for one it looks more sleek, I like that there is a big opening when lifting to feel, rearrange..ect.. without having to take the whole lid off.. and one of the nicest pros about glass is the water does not evaperate as quickly..
Sorry no link, I got my 40B glass lid at one of my lfs.. for $33.
