So I am trying to drum up opponents in my friend pool. I have seen the skirmish map playmats online for about $20, and thought I might pick one up so I can quickly get a game set up for an impromptu tutorial game when the opportunity presents itself.

What map in the available playmats would you consider a good one, with simple objectives, for the purpose of playing against someone who has never played? Maybe Training Ground, as that would give me the stormtrooper map/objectives if I haven't bothered getting the stormtrooper pack?

If you're just looking for a cheap playmat to facilitate quick play you can print your own (from any of the 40 released maps) from this project I work on. If you order a couple at once they get down to about $2 each map:

If you're looking for a recommendation from the official maps from tournament rotation that have been printed into mats, I think the recently rotated-out ISB Headquarters is one of the the most balanced and is one of my favorites to play. Without getting too nitpick-y, Training Ground is pretty good too.
