A DIY mechanic wants and needs to know all about their car, and a proper diagnostics program/unit is therefore invaluable. I opted for the iCarsoft Diagnostics unit v3.0. I will probably look into Xentry/DAS in the near future, but having this small powerful device in the car is a godsend.
Its powered by the car, so essentially hassle free! Don’t forgot to update the unit using the software on the iCarsoft website.
