Phil,
In the short rerm you may be quite happy with the Pectel Engine Monitor (PRO version)........It's not a bad unit at all....
BUT when you see a NEW monitor that will be in production in a few weeks time you will kick yourself untill your shins bleed - I've seen the pre-production version - I'ts in another leauge to ANY monitor that had been produced to date!! It would not look out of place in a £ 100 + k Ferrari/Porche/Lambo either
