Talk about deja vu all over again...
I just went through all that.
I made sufficient budget available to get THE mitre saw I wanted, damn
the expense.
I also took my sweet time. Did the FAQs, did the DAGS.

In my countertop business, I see a lot of kitchen installers...drove
them nuts with questions... played with their saws.

These things are highly personal, like fire-arms. Once you decide on the
size of the game, you can eliminate a whole bunch of mitre saws right
away.
I simply could not envision ever needing a 12". I worked with a 10"
Delta, no slide, no tilt for over 20 years with some pretty decent
results, including a few thousand feet of crown. (If I had a lot of
outside angles on bigger crown, I'd bring my trusty 12" disc sander for
that ultra-tight fit... tighter than a frog's ass and that is
water-tight.)
A 10" with a little extra slide, will make up for that little bit of
diameter of the 12".
12" blades cost more and the 10" field is far more competitive; much
more selection in 10" at much better prices.
Portability wasn't going to be an issue, as any saw was going to get
mounted on the RIDGID Mitre Saw Utility Vehicle Model AC9940 because it
is functional, cool, handy, solid and nothing I could build for that
little money. (About $ 150.00 US)
99%+ of my cuts would be small stuff anyway and saw no need to wind up a
few extra pounds of whirling steel. Those big wheels just don't feel
'surgical' to me.
So.. a 10" slider it was...

Bought it...and boy am I happy.

woops... bought the Makita LS 1013. Much nicer than the Ridgid.
