I'd been contemplating getting a DIY grade scanner for some time. It's clear that the electronic systems of cars are growing ever more complex and the ability to manipulate things like EPB, SAS, etc is ever more important. After watching many reviews, I'd pretty much settled on an MX808. Since that model is on its way out I found the MX900 with more features, and a price quite a bit less than anywhere else. Called asked some questions, made the purchase and it showed up on my porch the next day... Learning how it will benefit many aspects of testing / troubleshooting / maintenance.
