FWIW, I am a rookie DIY detailer, had a PC 7424XP, was not thrilled about it bogging down if I didn't exert 'just the right amount' of pressure, lost it in Hurricane Sandy (water damage) and opted for a Meguiars model which I plan to use this coming spring. My hopes are high for the Meguiars G110v2 . I like the direct pressure which can be applied with the bail handle and the fact that it has a 'cruise control' clutch thing that may assist maintianing pad rotation across a wider array of varying pressure throughout a polishing job.
