I have one. Used to use (still have, somewhere) the smaller Leccy Beccy but the dust collection was non-existent. Someone I know was selling up and going travelling, so I took the Kapex off his hands; nice saw, decent dust collection, and very lightweight for the size and capacity - that's important to me because I run around building stuff in people's houses. If that isn't important and you're looking for an essentially static SCMS for workshop use, then I think there are now alternatives from other brands that match the Kapex for accuracy and build - not sure about dust collection though, and the little touches (dual lasers, the angle finder) make it a pleasure to use.
Having said that, I wouldn't have bought one if it hadn't been priced right - I just don't use a mitre saw enough to justify the cost if bought new.
@ chippy1970 - who was the dealer Chris? Any other bargains going??
