KVM Switch Questions

Not 100% sure if this is the right place (if not I apologize, and please let me know where to move this to). I am posting here because it is graphics related (sort-of)

Want to get an idea on what type of KVM switch I should buy? I know I can ask 100 people and get 100 answers, but for this case I am wondering which brand I should look for, and what should I avoid?

The type I am looking for is as follows:
1 monitor, 2 computers, PS/2 connections for mouse/keyboard, push button control, cables included
Resolution: currently running 1152x864 so that is the min
Price: Less then $50

Optional would be:
Audio, hot keys (as long as it has the button)

Any thoughts?
