Honestly the groups I've played with don't really use miniatures. We tried for a while with one of my Father-in-laws campaigns, but only one person in our group liked it, and my Father-in-law didn't.
For that game I was actually playing the Kalashtar Psion I've mentioned in previous posts. I don't know where the figure was from but it was a sorceress figure or something of the like that my Father-in-law had in his box of figures. I did use a figure of my own though to represent my construct, as I tended to focus on that. It was an Obsidian Guard figure from Heroscape.
