I saw that they just released a window suction mount for the Apex Pro. This was a sticking point for a few folks i talked with that didn't want to permanently mount a base on their dash and risk possible damage if they needed to move it (or remove it). I didn't have any trouble when I removed the base for my demo unit, but this window mount would let me take it in another car, like a student or a friend.
I also found out that Just Track It is offering a deal (no affiliation, just passing the word), if you register for one of their track days you can put $50 of your registration toward the device and effectively get a $50 discount. More details at the registration page on clubregistration.net for their events and possibly on their site at justtrackit.net.
