Connecting MBP w/Retina and Work Laptop with Switch to dual monitors

I have the latest MBP w/retina display and NVidia GT750M video card. I also have my work laptop (Dell, Win 7, HDMI out). I want to connect these to a dual monitor setup with a switch. I currently only have one monitor that is 1920 x 1080 and supports hdmi and dvi. I would like to buy another cost effective monitor to take advantage of my MBP's higer resolution and have that as my main monitor.

Next I would like to connect the two laptops to the dual monitor setup via switch to go back and forth between systems.

What is the best switch to buy for my needs? Does OS matter when selecting switches? Monitor recommendations are appreciated also.
