ProScan? Worth it?

It's a great inexpensive basic scanner... however it can't read GM Enhanced parameters (knock retard being one of them) ... it can read codes and clear them (not delete since it's not a tuner), and scan basic parameters
at least this was the case last time I checked... if it can read GM Enhanced params then it'd be a great entry level scanner... otherwise I'm not a fan...
