I have the 618 and a Hitachi, both the combo sets. The Hitachi is used in a table and for circle cutting. The Dewalt is used for everything else. A good friend has the Bosch, which I almost purchased over the Dewalt.

Between the Bosch and Dewalt you will likely be happy with both, I think they are both fantastic. The Hitachi I bought used for $75, and it is actually really really good too. If I could save $50 getting the Hitachi I might do it.

That said I like the handles on the Dewalt as the Bosch handles started to feel really slick on a hot day doing longer passes. The plunge base on both is really good, though I feel like the Bosch got sticky over time. The removable cord on the Dewalt is really nice, way more of a differentiater than I imagined that it would be.

Like I said, both are fantastic, and more than enough for a casual hobbyist. The Hitachi, in my opinion, would be a great fit as well.
