This is the superceded model. New model has REB suffix. Difference as far as I can tell is dust port and stabilization arms. I cannot find any reports on real world difference.
I've just spent my shop money elsewhere but if I haven't…
$250 off retail. Festool rarely goes on sale.
Description from website (although if you have to read this, this item is not for you).
The KAPEX Sliding Compound Mitre Saw is a true example of Festool's innovation. It's unique design allows maximum cutting capacity of the 10" saw blade, enabling you to cut 120mm high skirting boards at their finished angle. Dual-line laser beams clearly mark the exact width of the cut for positioning the work piece from the left or right. Fine adjustments give millimetre precision for angle and bevel cuts, and the twin sliding rails ensure smooth guidance of the saw blade for the perfect cut. The compact design means no space is required behind the saw, allowing you to work easily in restricted spaces. The KAPEX is covered by Festool's comprehensive 3-year warranty.
