I went from a beginner 16" to the Delta P-20, so that was quite a leap forward. I was sure that I wouldn't find anything better which is why I really hesitated to get something new. I really lover the Delta. After much research and getting input from everyone here at SSV I took the plunge and got the King.
This thing, for me, is another leap forward in my scrolling ability. I've had it for about 6 months now, took some time to tune it, again the people here on SSV were invaluable to helping me get that done. But I gotta say I really love this saw.
If you're thinking about getting one, don't hesitate, go for it!
