Hi Red,
I've had a KG 331 for a couple of years now. As you mention not the cheapest but well worth it for build quality and performance. When I did my research I had a few models to consider - Dewally 702/3, the Makita slider and the Scheppach Capas model. Went for the Scheppach. Great capacity but noisey and a bit on the big side. Kept it for 6 months and sold it. Back to square 1 - bought the DeWalt, played with it for a day and gave it back to the dealer. Wasn't a lot wrong with it, just didn't like it and too much plastic bits on it. Went to look at the Makita LS 1013, great saw, accurate, trenching ability but at £550 or so, couldn't justify it. Happened to be at a demo day at a dealer and saw the EB KGS 331. Had a go on it, bought it and took it home. Think it was about £350 or so with stand and dust kit. Plus points - INDUCTION motor nice and quiet, hardly any plastic components, very accurate, easy to use, good and heavy, reasonable dust collection., great width capacity, smooth and rigid slide action. Not so plus points (but not a deal breaker) - left bevel only (due to being direct drive and induction motor is a bit bigger than a brush motor), depth of cut limited to 50mm at 90, no trenching facility.
All in all mighty happy with it and would buy again. Original blade was ok too but now replaced with a Freud LP40M that leave cuts like glass. Providing you appreciate it's slight limitations you cannot go wrong.
Feel free to ask any further Qs.
