Just the regular one - $90 at MacMall.

I'm pretty sure the aviation one is the same unit with accessories bundled in.

Yes, it is the exact the same hardware. It just includes the friction mat and the 6 month trial of Garmin Pilot®. Unless you want the software, it doesn't make sense... you can buy the mat for $15 at Garmin, or use your 10% discount code when you register and get it for $13.50.
