If you spring for the SD-508 you won't be dissatisfied. I originally purchased the 208 series and "unloaded" it on Gofor last spring after I stole the 508 from an unsuspecting Ebayer. Absolutely nothing wrong with the 208, but since you're saving money (saving...yeah...spending is more like it) pop for the 508. My set is dead on accurate in width when you assemble according to the directions, but sometimes the depth of cut is off a little. Still working on that.
