Hello, the question about polishing machines has already been asked a thousand times. I already know which machine I want, but fluctuate between two devices. And it is the eccentric polishing set XC 3401 VRG and the polishing set L 3403 VRG from Flex. What kind of beginner who has not worked with any machine would be the better entry and where are the machines differ technically and price? As I said, I am completely new in the area of polishing machines. It would be nice if you I can help with the choice between the two machines. Thank you very much.
