I'm planning to purchase my 1st DA. I will be using it to maintain a 2003 Nissan SUV (which has moderate water marks on top of the roof and hood, and some light to moderate scratches) and a 2011 Honda Fit. In terms of specifications, it's a no brainer to choose the GG 6 over PC and Megs. My only concern is the reliability of the GG 6 since I will be using it in Asia. I wanted something reliable because sending it back to the USA for repair/warranty will be very expensive. I really want to get the GG 6 because of its power but I have been reading some posts that it is not the most reliable tool compared to a PC. I was thinking that the reliability issues might be user induced or improper usage of the GG 6. Do you think I am better off getting the PC 7424xp? Will I have the same correction abilities (for water marks and scratches) for both machines? I don't mind spending more time with the PC just to get the same results of the GG 6.
