My 26 yr old 8 1/2" craftsmen slider bit the dust late last year, so i too, went on the hunt for a new one. As I sometimes make 16" deep standing cabinets, I knew I wanted a slider, and looking at the reviews, the DeWalt 10" seem to be the best buy. I like to get a hands on look, but the only place I could find one was on-line. About a month after New Years, Dewalt put a deep discount on some of their saws, (not the 10" I wanted) and Lowes had the 12" dual bevel slider for less than the 10", so I bought one.
What I like:
It is very accurate, and only needed very minor tweeking to get it dead on. I have it on a mobile stand, and it has not come out of alignment in the 6 months I have had it.
Very solid with no deflection at the extremes of the slide (without a hard deliberate sideways push, which will only cause about 1/32")
It has adjustable stops, as well as preset ones for both miter and bevel, which are quite convenient.
It has removable vertical fence sections (which are dead on vertical),
It has a blade light that you can switch on or off (not tied to the blade switch.)
The blade that came with it does an excellent job, with no wobble.
The handle with the safety switch is easily used with either hand
Full 4" depth of cut behind the blade center, and 3 1/2" under the blade washer when in the full down position and slide cutting.
What to be aware of:
It has a noticeable kick up when you trigger the saw. If you set the blade down on your work to align the outside of the tooth shadow with your cut mark, and then trigger it just above the work piece, that kick up can cause you to instinctively over-correct, bouncing the blade off the work.
It has a large footprint.
What I don't like about it:
The hold down clamp is useless. The table is slick, and the clamp so wobbly, that the work easily slides around even when tight, and when you tighten it, it will push the work away from the fence. There is a "flexible" chute for the vacuum tube that will knock your work off the fence when you draw the saw all the way towards you in preparation for making the cut.
If you use vacuum, you will need to also buy DeWalt's adapter ($20) to hook up a standard 1 1/4" vac hose, and another $10 adapter if you want to hook up a 2 1/2" hose. (Neither is included with the saw)
When hooked up to my Ridgei=s shop bvac, it does a pretty good job of containing any sawdust from behing the saw.
From what I can tell, both these issues also apply to the 10" model.
Overall, I am happy with the saw: its accurate and solid construction. (and I was able to get it discounted about $150). If you won't be cutting 4 x 4s or 16/4 lumber, the 12" is probably overkill.
