Travel Tools - AutoSlash anyone ?

After a mention by Arthur Frommer some time ago and now this (http://www.nytimes.com/2012/02/18/your-money/autoslash-a-rate-sleuth-makes-rental-car-companies-squirm-your-money.html?pagewanted=all)article in the NYTimes, my initial curiosity is revived again and I've reserved a 14-day car rental in Europe.

Anyone have experience with this booking engine for a reservation over in Europe and if so, how did you fare as compared to AutoEurope, where I normally book my rentals ?

TIA !
