VGA splitter

I'm looking for some kind of extension for VGA but I don't know what to search for.
Heres the scenario, on my desk I have a MBP and an Xbox 360 hooked up to a 17" LCD monitor (I plan to purchase a decent sized one once I actually have some money). What I would like to do is have a splitter plugged into the monitor, so that I can plug in both the Xbox and the Mac and toggle between them. It should be possible because I have a similar setup on my TV downstairs, just with SCART cables instead, I have 5 going into one socket. So if anyone knows of something I could use (which is relatively inexpensive, or I might as well wait until I get a new TV) it would make my life that much easier lol.
Thanks in advance

Something like this?

It's ugly, but it or something like it would work

Hmm link didn't work. Found one though here http://www.amazon.co.uk/dp/B000J249JC/
Yes it is ugly, but you should see my monitor This is more of a temporary solution until I can afford a new one.
Thanks anyways
