Switches, like cables, are way overpriced pretty much everywhere. Except monoprice:
Read the knowledge base page on there while you are at it. What they say there is 100% true. And that switch will work as good as any. Also, AFAICT, this switch has all of the same features as the $299 one linked above, though don't quote me on that as I haven't owned this particular one. 22 user reviews say it is a good one however.
