I bought the 12" around a year ago and I love it! I have not used the 12" greater capacity often, but I have a few times and I was happy that I had it.
Incidentaly, my 12" blade speed is 4000 RPM, both in the booklet and on the sticker on the saw. But I have checked their website and it does indeed look it is now 3600 RPM.
Maybe you can still find one of those older 4000 RPM units in some borg stores around...
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...
