Agree with everything Sean says!
Lauch I have seen used several times and had demo'd at least 3 times from memory and have never ever been impressed by it. Used to own a Solus before the Pro and Ultra and found it to be OK as an entry level diagnostic device but irritating with the personality keys. The 'simple' yes/no interface made it complex and slow to use. We trialled and demo'd loads and settled on the KTS670 Bosch as the information on there is fantastic and it's abilities are close to dealer level on a lot of vehicles.
