It's $370. It still rents for $70 for a weekend or $50 for a single day. So just over 5 weekends and it pays to have bought one. Except this is a 1st generation machine. I'm betting that they're already working on a better unit.
I had thought about renting one last year but they had problems in the Demo tent they didn't know how to fix so I wasn't all warm and fuzzy to drop that amount of money for something that may not work. I'd hate to have bounced the darn thing off of a certain red car due to frustration. I stuck with my lil' cheap scanner.
They told us at Lowe's Motor Speedway that you have to give them a credit card to hold. If you drop it or it gets wet or something and gets ruined they will charge $500 to your credit card.
