As a birthday gift two years ago, I got the original 7424. I've used it on two cars total, and on the third car, (tonight) it broke. the shaft that holds the counterweight to the body of the polisher sheared in two. in fairness, it could very well have been my fault for applying too much pressure. i'm sure it could be repaired, but is it even worth it for the price of the XP or g110? I never was really that impressed with the power behind the 7424, and i'd love to have a flex, but i can't really justify spending three times as much money on something i'll use twice a year. thoughts between the g110 and the xp? i'm sure the topic has been beaten to death...
