Visio Replacement?

I need to do some quick and dirty floor plans of server rooms. I normally use Visio and I was wondering if there was a MAC replacement someone can recommend. I actually hate Visio so any chance to get away from it would be a welcome change.

Thanks.

There are some diagramming bits of software out there, 2 off which are open source

Inkscape http://www.inkscape.org/index.php?lang=en

DIA http://live.gnome.org/Dia

You may also have OmniGraffle installed already on your Mac

Try OmniGraffle. It's not cheap, but it does a great job.
