Below is my review of the Flex XC 3401...It also includes a video comparing the cutting ability of the Flex to the PC.
Here is the link to the review (the video link is at the bottom of the page)
Flex XC 3401 VRG Review
This is a great machine to step up from the PC & IMO narrows the gap between the PC and a rotary. It has great cutting abilities and will cut polishing time down substantially if moving up from a PC.
Enjoy
