I was looking at the exact same decision. I only looked at the Rigid R4510 as part of my due diligence. I was sure I'd buy either the DeWalt or the Bosch. I could find hardly a bad word on the Rigid. Both the Bosch and the DeWalt had very good user revues. But, they had a lot of comments on being set up poorly from the factory. Tune them up, and most were OK. The Rigid had none of those problems. After looking at the R4510, I picked up that saw. I have used it quite a bit for the past 2 weeks. I'm very happy with it, and it was perfectly set up. I haven't found 1 thing I don't like about this saw.
