I bought one recently and thought it was an excellent machine until I used it as a second router for cutting dovetails on a Leigh jig. The problem is that the needlessly complex device that holds the guide bushing defects about a thousandth and a half under pressure which results in surprisingly large gaps in the DTs. I can't imagine why Bosch came up with such a rube goldberg mount unless it was so they could sell them. In any case, I have one of Pat Warner's bases on order and that should fix things.
