I do dig those rearmounted motors. They allow a dual bevel too.

You should check out the Makita 12"SCMS. The most recent issue of Fine Wood Working did a comparison of 12" sliders and this one rated highest (the Bosch was a close second).

The past 3-4 years, the Mak and the Bosch have run neck and neck in the SCMS category.

Either co makes fantastic products.
