I
love mine. Two good friends of mine, both self employed contractors have them. The German cabinet maker uses his for on-site work. The big selling feature is the rack and pinion fence, can't be beat.
7/8" dado stack isn't a problem. When I make my rabbets and frame rest cuts though, my German friend showed me how to do it properly, with the wood on it's edge rather than laying flat. Way less tear out that way.
Also you don't need to stack near as many blades on the saw that way.
This pic is using his shop saw.
