My group started out playing Pathfinder (transitioned from D&D when the 4E nonsense came about) and we've got a large collection of the D&D Miniature models that we've collected and tossed into what is affectionately referred to as "The Critter Box", so we use those if want a physical representation of everyone on a map. Sure, it doesn't exactly fit the theme, but we can at least identify that the mage figure is for the magician, the big burly orc is the brawler, and so on.

Now that we've come to the realisation that the 50" TV that we're been sitting in front of for quite some time can be plugged into my laptop and used as a second monitor, we've taken to using mapping software and placing markers on there to show everything. Much easier for everyone to see than the setup we had used before (a grid of 1" squares covered with plexiglass so we could draw on it with a grease pencil which was hard to see some times if you were in the wrong spot), plus I can throw up player handouts, reference documents, and anything else I need without having to remember to print it (I keep forgetting), or finding that it would be helpful for them.
