Never been impressed with the Launch stuff...
Love the Bosch equipment. So easy to use and so much info with it.
Used to have a Solus. While it was ok at getting into diagnostics it was that simple to use with the Yes/No interface that it made it long winded and a pain in the arse to use. Sold it on for a KTS670 and never looked back. The newer Snap On stuff is coming through with touch screens on now and better user interfaces so they are a lot nicer to use but obviously they're not really in your budget!
Sean, the KTS should be getting a JLR shot in the arm over the next few updates.
