O\O Code Scanner Options

[TBEV]

I just bought a 08 Pete 386, ISX15. I'm wondering if as an OO should I also own a scanner of some kind? I have been reading up on the forum and it seems to me that Cummins Insite is the way to go. Can anyone with experience tell me the differences in the versions; lite etc, I'm assuming one will just read codes one will allow me to clear them. I do a lot of work myself on the truck, I would like to stay out of the dealer as much as possible obviously, I've been driving my '85 359 for the last 30 years, finally had to give into and buy a new ('08) truck.

Is scanning \ clearing codes enough?
Is there a cheaper scanner option that will just read \ clear codes by it's self?


Thanks in advance.
