I went with the 4hp, with 36" fence. I did not opt for the coating.
Things I like:
Larger table and more room in front of blade.
Fit and finish is "pretty good"
Miter gauge is absolutely amazing for out of the box miter gauges.
Fence is smooth as silk, though I am probably never going to use the low fence setting. Would've rather had a UHMW fence, knowing my history with cutting into my fences.
I upgraded from a 3hp model and though it's only 1hp more... it was totally worth it.
What I don't like:
Dust collection sucks. I mean, I won't even hook up the over blade contraption. The small port steals too much vacuum for it to be effective. As it is, the dust collection from underneath is very sub par. I will likely re-work the whole system by cutting a 6" port and increasing the inside hose that goes to the blade shroud to at least 4". Anyone that is expecting better dust collection (and currently has a serious dust collection system) will be disappointed.
Overall, the saw is an upgrade to what I had and I am happy. It was between this and the saw stop.. but I just didn't see the point in paying so much more for a feature I have, to this point, never needed in 35 years (some professionally) of using a table saw. I guess I could feel safer while spending all that extra money on brakes and blades all while waiting for new parts. ... and blades.
Anyway, Harvey is a 4.5 outta 5 for me. I think it's a good saw, that needs some woodworker input to get them where I would want them.
