I did not buy a jeep scanner, but other brand this past spring for $800. Yes, it has paid for itself. Whether jeep specific, or generic which handles other car brands, a good scanner is worth it weight in gold. Expect 3 year life, and hope for more. Yes I recommend real dedicated hardware for scanners. I also have ANDROID apps for mobile use, and WINDOWS PC hosting BMW and FORD specific tools. I had hoped to reduce my scanning/code hardware and software, however it seems the more I learn, the more hardware and software I acquire for my fleet. Scanning and the use of a scope is indispensable and takes time to learn. Not a 1 day I know it all, doesn't happen.
