Hello Bill. I own both a Pscan and a Classic MPI Mini ( Not Japan Spec ) . We have owned the Mini from new ( 22 years ) and the Pscan has been an excellent diagnostic tool and I wouldn't hesitate to buy one . There are very few diagnostic tools as good as Pscan apart from the original MG/ Rover Testbook and the Sykes Pickervant ACR4 . Both these are very expensive to buy ,if you can find them !
